I think this is good because I didn't read this part of the whole story... Although I was actually thinking if you report someone else post they may feels is that person's alt account so this made me to stay clear from other people's post.
I think it was even the report other users posts that was clearly emphasised in the OP's post rather than reporting one's own, although all of them are still on the rules and not against the rules anyway.
I just realized that most members might also be thinking and picturing things the same way you viewed them in regard to others thinking they are reporting the post from their alt or something of that nature, but those shouldn't really be a limit or reason to not report it as everyone has different opinions over things, and you being the users who reported those posts knowing fully well that they are free from such allegations shouldn't bother you at all.
