Part 2: The "Avatar Aesthetic" Vocabulary

Slender
- Appearance: Tall, thin avatars with elongated proportions
- Typical Style: Often black/white clothing, "edgy" aesthetic

E-Girl / E-Boy

You will often see messages that are nothing but "####". This is Roblox's "Safe Chat" filter in action.
How the Filter Works
Roblox uses an automated AI system to scan every message before it's sent. The filter checks for:
- Profanity: Swear words and vulgar language
- Personal Information: Phone numbers, addresses, email addresses
- External Links: URLs to websites outside Roblox
- Sexual Content: Any sexually explicit language
- Harassment: Bullying, threats, or harmful language
- Scam Keywords: "Free Robux," "password," etc.
When the system detects something problematic, it replaces the entire word or phrase with hashtags (`####`).
Frustration is Common: Kids often get frustrated when harmless words are "tagged" (filtered). If you see them typing "TAGS" or complaining about "the filter," they're frustrated that the game is blocking what they're trying to say.
Age Matters: For players under 13, the filter is MUCH stricter:
- Most numbers are blocked (prevents sharing ages/phone numbers)
- More words are filtered
- External links are always blocked
- Even some innocent words get caught
The Filter Isn't Perfect:
- Some inappropriate content slips through
- Kids find ways to "bypass" the filter (see next section)
- Context matters (some words are okay in certain games)
---
Part 4: The "Bypass" - Red Flags to Watch For
Because kids find the filters annoying, they often try to "bypass" them. While usually innocent (like trying to say their age), this is also the method used by bad actors to say things they shouldn't.
Common Bypass Techniques
Letter Spacing:
- Example: "h e l l o" or "f r e e"
- Why: Spaces between letters confuse the filter
- Risk: ⚠️ Could be innocent or could be hiding something
Number Substitution:
- Example: "H3ll0" or "Fr33 R0bux"
- Why: Numbers look like letters but bypass filters
- Risk: ⚠️⚠️ "Free Robux" is ALWAYS a scam
Special Characters:
- Example: "f.r.e.e" or "f-r-e-e"
- Why: Periods and dashes break up flagged words
- Risk: ⚠️ Worth investigating
Phonetic Spelling:
- Example: "phree" instead of "free"
- Why: Sounds the same but spelled differently
- Risk: ⚠️⚠️ Usually trying to say something prohibited
Unicode Characters:
- Example: Using special symbols that look like letters
- Why: Advanced bypass technique
- Risk: ⚠️⚠️⚠️ Deliberate attempt to evade filters
Major Red Flags
If you see these patterns, investigate immediately:
🚩 "Check My Profile/Bio"
- What it means: They're trying to share information outside chat
- Why it's dangerous: Profile can contain links to Discord, social media
- Action: Tell your child to never check strangers' profiles
🚩 "Add Me on [Platform]"
- What it means: Trying to move conversation off Roblox
- Why it's dangerous: No moderation on other platforms
- Action: Reinforce rule: "We only talk on Roblox"
🚩 "I can give you [item/Robux]"
- What it means: Promising free items (always a scam)
- Why it's dangerous: Attempting to trick your child
- Action: Teach: "Free Robux doesn't exist"
🚩 "What's your [personal info]?"
- What it means: Asking for age, location, school, etc.
- Why it's dangerous: Gathering information for grooming
- Action: Teach: "Never share personal info"
🚩 "Can you keep a secret?"
- What it means: Grooming behavior
- Why it's dangerous: Building inappropriate secret relationship
- Action: Teach: "We don't keep secrets from parents"

Part 5: The Economics of Chat - Trading & Scams

Trading Acronyms

Common Trading Scams
Trust Trade
- How it works: "You give me your item first, then I'll give mine"
- The scam: Once they have your item, they leave or block you
- Prevention: Teach: "Never trust trade. Always use the trade window."
Switch Scam
- How it works: Scammer shows one item, then quickly swaps it before you accept
- The scam: You accept thinking you're getting something valuable
- Prevention: Teach: "Always double-check the trade window before clicking accept."
Fake Value Scam

- The scam: Item is actually worth much less
- Prevention: Teach: "Check values on trusted sites, not from traders."
Free Item Scam
- How it works: "Free rare pet! Trade me your [anything] and I'll give it back!"
- The scam: They take your item and leave
- Prevention: Teach: "Nothing is truly free. Be skeptical."
"I'll Level It Up" Scam
- How it works: "Give me your pet, I'll level it up and give it back"
- The scam: They keep your pet
- Prevention: Teach: "No one can level up your pet except you."

- Set boundaries: "No romantic roleplay until you're older"

Context: Usually happens in competitive games when players are arguing.

Cap / No Cap

Part 8: How to Talk to Your Child About Chat
Now that you know the lingo, how do you use it? Here's a strategy for approaching the topic with your child.
Strategy 1: The "Translation" Game
Approach: Instead of being the "Police," be the "Student."
What to Say:
- "I saw someone typing 'ABC for a dog' today. What does ABC actually mean?"
- "What does it mean when someone is a 'bacon'?"
- "Can you teach me some Roblox words?"
Why It Works:
- Lets them feel like the expert
- Keeps communication open
- You learn without interrogating
---
Strategy 2: Discussing the "Filter Frustration"
Approach: Empathize with their annoyance.
What to Say:
- "I bet it's annoying when the hashtags block your message."
- "What are you usually trying to say when it tags you?"
- "Why do you think Roblox has these filters?"
Why It Works:
- Shows you understand their perspective
- Opens discussion about WHY filters exist
- Helps you monitor what they're trying to say
---
Strategy 3: The "Safe Exit" Plan
Approach: Give them permission to leave uncomfortable situations.
What to Say:
- "If the chat ever gets weird or creepy, you don't need to explain yourself."
- "You can just leave the game immediately—no questions asked."
- "I promise I won't be mad if you tell me something uncomfortable happened."
Why It Works:
- Empowers them to protect themselves
- Removes fear of getting in trouble
- Creates safe reporting channel
---
Strategy 4: Regular "Chat Check-Ins"
Approach: Make it routine, not reactive.

Why It Works:
- Normalizes the conversation
- Catches issues early

---
Strategy 5: Role-Playing Scenarios

Why It Works:
