Let me put it in a list...
- You know those people who don't know where to put their periods and commas? Yeah, I hate it. It's so annoying. That can also include those people to have spaces after their quotation marks and punctuations. I.e.: " Thank you so much ! "
- Those people who godmod. Enough said.
- Grammatical errors. I think browsers have spell-check now, right? I don't care if it's a little misspelling due to typing fast, but if it's huge mistakes... ugh. Makes my eyes bleed.
- Too many OOC conversations. But I might be a little hypocritical, since I, myself, am guilty of this.
- Putting too many emoticons. Personally, I've never seen someone here who RPs with emoticons, but while I was still on Facebook... I really want to dunk my laptop into boiling water when I see those. Of course, I didn't dunk it.
- Those who try to incorporate [insert genre here] on a strictly [insert genre here] RP. It just irks me a lot.
