1. When the mods and admins only come on to lock, ban, and make site changes and never just chat with others.
2. People who overuse animated smilies and make dial-up connections go berserk.
3. Forums where all the text marquees.
4. Wen mods n adminz spel lik dis.
6. When people do not use correct spelling or grammar. It annoys me to bits when people don't start a sentence with a capital letter, it's just sheer lazyness.
8. Really odd rule enforcement. Where the mods get really strict over minor things, yet let members who act like jerks and treat others poorly get by.
9. Members who make really short posts with little substance.
I have quite a few peeves; all of which I have seen at one point or another.
1. Inactive staff
2. 1337 speak.
3. Moderators who play favorite to certain members.
4. Overly strict staff.
5. Extremely pretty layouts, while the site has no substance
6. Admin and moderators who do not talk to their members.
7. Power trips
8. Lazy staff
9. Horrible spelling, grammar, and punctuation.
10. Posts with no thought or effort behind them.
I don't really have any pet peeves besides the owners having power trips or being controlling or the forum being unreliable (unlike FP, that is out of 4 people's control)
