I got permabanned from /r/askhistorians for posting a link to reveddit, a site where you could view deleted posts. I did that to inform people that they could use that site to see all the posts that the mods remove (in that subreddit they remove any post that does not provide references).

I thought that the worst case would be that my post would get deleted and I would get a warning. No, they just permabanned me.

I was mad so I appealed telling them that it's wrong to permaban people for reasons like this. I understand permaban for offensive content. But I still don't understand their action.

Discussing with them proved that while one of them one reasonable and understanding, the other was completely mad about my action and wanted me to be almost on my knees pleading to remove the permaban. Eventually they "did a vote" and I stayed permabanned. I tried again one year later to no avail - I figured, maybe one year later they would get over it. Nope.

I just stopped checking and recommending /r/askhistorians ever since.
