Why it should be stopped:
F4F is when you follow someone just so you can get a follow back. It's just being greedy for fame most of the time. Even if you are doing it to be friends, why would someone want to be friends with someone if they sound like they are begging for followers? You can just type "Hello ____! Do you want to be friends?" instead of "Follow me and I will follow you back!"
Another reason why it should be stopped is because it's annoying. Imagine how many F4F comments people like @WazzoTV or @griffpatch get a day? Giving famous Scratchers a follow is nothing compared to what they're giving you. You would get tons of fame just because you were followed by them and they would get a one more follower when they have hundreds anyway.
-NO ASKING F4F! If you want to do F4F, go to a F4F studio where they allow you to F4F.
-Only add Anti-F4F projects.
-No changing picture without showing @DisasterPug first.
-No F4F done in the last three months and doesn't do F4F.
-Not banned from studio (I keep a hidden list of banned users)
How you would get banned:
-Breaking the rules.
-Started to do F4F after in the studio.
