Didn't officially act as a mod, but I think it's fair to note this down: spotted a NSFW link in a post of Seitora's outside the NSFW section after a report, but before I could point that out to him and have him edit it out, he deleted all the links due to broken hotlinking, so I left an unofficial suggestion message from fellow user to fellow user in that topic.
The post in question, which is now NSFW-free, is this:

The post I made in response is this:

The rule that came into play is the one concerning no NSFW material outside the Restricted section.
...god, I suck at making official reports. Is this satisfactory?
