You could easily hit 5000 reports a day if you were dedicated to the course in the altcoin section, and many users are reporting hundreds a day. I've woken up to reports in the thousands some days, and a lot of them are coming from the altcoin section. The place is absolutely incredible, and unfortunately good discussion does get lost there.
5000 reports per day is absolutely incredible and would make the moderator shit in his pants. The problem with most of the reporters is that, they report each and every post if the user spams the forum continuosly. This shouldn't be encouraged. Just reporting one and commenting to take a look onto the spammer's post history would do good. Similarly if a topic is filled with referral spams, it would be better to report one and comment to look onto the other posts in the topic. With this, the moderator might trash the whole topic without just viewing each and every report. Once last year, I have seen that mdayonliner reported more than 200 posts per day made by the same spammer and hilarious PM'd him to just report one and leave a comment.
I was active in the Altcoin Section last year helping people on technical questions. But its just absolute waste of my time searching for one good topic for 30-40 mins. I just left that place once for all unless theymos creates a Tech Board for Alts or something like Serious Discussion for having good discussions about Alts. Same as btc, I am interested in the tech of the alts too.
I don't really understand how you are moderating such a massive frog pond and keeping them clean with you being the only moderator apart from mprep.
If anyone does come up with an idea which would encourage others to report more without the drawbacks discussed then I can absolutely get behind the idea.
If anyone is really concerned about the health of the forum, they would surely report no matter what they receive in return.
