Public service announcement: regarding icon thieving

I’d thought earlier that I’d be entirely forgiving of icon thieves but having come across yet another one of my edited icons in use somewhere else with no credit; it’s actually starting to annoy me. I don’t even do much more than colourise, airbrush or change light density a little and add boarders so you’d think these people could just do that themselves rather than stealing mine instead. But apparently not. Trinity Blood Forum and unspecified multi-fandom RP; I’m looking at you.

Asking would be polite but credit would be acceptable. Or are manners truly a thing of the past in this day and age? I’m beginning to suspect that they are.
Humanity really is beginning to disgust me again in those lovely little increments that remind me that polite daily conduct is too fucking hard for some people.

And as per my last post on the matter; icon very deliberately used for this one.
