Roleplaying Communities and Cliques.
The one thing I am sick and tired of is the conglomeration of cliques going around. There are tons of people willing to make tight knit groups. This is understandable as the number one perk of friendship is to have a group of like-minded people willing to accept you for who you are. It becomes a problem when you not only make trouble for other users on the site, but you intentionally make it your groups goal to raise hell in a number of rooms. The fun part of roleplaying sites is to meet like-minded people and share a world you and that partner create to make things better. It becomes an issue the moment you tend to shut others out for the sake of a group, complain that no one whats to roleplay with you and you're always bored, and then constantly rinse and repeat. It's worse because every member of said group does the same exact thing.
You want different? Accept difference. If you wish for a certain thing and that certain thing shows up on your doorstep like a convenient gift basket, maybe take the time to actually give it a shot. If the new partner you let in doesn't appeal to you THEN you can immediately decline and block. However, I find it hilarious that almost every room I go into has these "I'm so boooored! I can't find annnnyoneeeee!" type people, but only stick to their little clique. Never wanting to branch out or give anyone else a shot.
