Especially if the person you stole from is loved incredibly by one of the mods of a community you're trying to join.
All my icons are freely gackable. Go for it. Steal your little hearts out. This is a PERSONAL decision, and only applies to MY icons, not icons of community members.
Also, spam sucks, keep it to a minimum. Unless you, say, forget to link the community you're spamming for and thus amuse us greatly.
