What if someone harassed/insulted/calling names in a comment, but an admin won't do anything about it because the comment was 2 months old? What can you do?

I tried reporting someone who had done that, and the admin won't do anything about because, in his words 'I'm not going to do anything about a comment that's two months old unless it links to illegal content or malware.'

I don't recall seeing that part in the Harassment rules section.

He did that once, two months ago. You've also been regularly here since that comment was made and thus had two months time to report it. On top of that it's also a fairly tame insult.

You can blacklist him if you want to but we're not going to discipline him. If he does it again feel free to report him in a timely manner.
