So far I've come up with only these people:
ShadowEye75 for some guy's unfair dm on my server recently.
LaLaM24 for something I can't remember and don't even know if he remembers.
Jannet for being, or so he said, "illiterate." (Hypocrisy was abundant at the time. :P)
Some of my friends for enjoying some of their enemies' company.
That's it for now.
