I posted a comment on the following question. My comment was:
You will have to work on your accept rate. Currently it's catastrophic. Zero as in a singularity inside a black hole.
This comment was deleted by someone. I would like to know if showing users that don't know how to accept answers is considered as a bad thing so that I stop doing it or if not why would my comment have been deleted and do only moderators are InRole to delete comments.
