For some reason this one always pissed me off -

Here's a few more lame ass names:
Cotton Candy. Even the members of this guild have lame ass fucking names.
Perhaps. Fucking bot guild. Always reminds me of that Cake song - Perhaps, Perhaps, Perhaps.
Sariahs Hope Gay ass name. When anyone names their guild after their character, they are a fucktard.
Knight guards and pretty much any guild that doesn't capitalize their name.
