I think this is a pretty dick thing to say. There is a huge difference between being a recovering drug addict and being annoyed at shitty alt coins with no value.

Assuming the OP is telling the truth then he it trying to get his life back on track after most likely hitting rock bottom. A monero avatar is noting more then a minor annoyance at the very worse.

in theory the OP could end up relapsing and ruining his life and/or someone else's life from looking at the avatar in question. You might end up being annoyed for another 2 seconds while scrolling past his posts after looking at his avatar.

There is a huge fucking difference. I am not sure if those kinds of avatars should be censored or not, however you need to learn to be much more respectful.
