Heads-up:
Since my lat post I cleaned the following topics:
Cleaned both - 343 reports. First topic was already cleand (I reported just 1 post from it). Second topic was a monster one, with 28 pages and I had to report 342 posts from it. Actually I had to report all 556 posts from it, but a mod was ahead of me and started to delete the topic posts before I had time to report them all

Now it seems the topic was entirely trashed. Great job mod!
Having these 2 threads cleaned as well I finished cleaning everything from page 2 of current topic. Now I am at page 1.
Cleaned all 3 topics - 522 reports. MASS was by far the most difficult topic to clean from I cleaned so far. First of all, it had 32 pages. Second of all, it was full with both good and spam posts, made also not only by newbies. I had to spend several hours to read carefully each post... Many were at the limit between spam and offering a useful information... It was horror to clean this topic! Absolutely horror!

I reported 468 posts from MASS topic.
Cleaned - 21 reports.
Cleaned - 35 reports.
Both threads as previously cleaned as I had to report only 8 posts.
I could not take care of this, as it's written in Russian. Maybe a Russian speaker can take a look.
Here I cleaned second topic - 26 reports.
Coco's topic was deleted, as I stated above, but the old one still exists and it has 103 pages. Emirex has 115 pages. I will leave for later these ones, together with the topic mentioned at post 12 (Modul topic), lattest one having 251 pages. After I finish cleaning all remaining topics I will take care of these 3 monster topics too.
This thread was also cleaned, as I had to report just 1 post.
All in all,
I reported 845 posts from all these topics!
The only topics remaining to be cleaned (together with the 3 ones mentioned above) are: Crybet, the one from post 6 and the ones from post 3 (four topics), meaning a total of 9 topics. They may seem few, but they have 592 pages and more than 11.800 posts to be checked

I'll try to sort that out this weekend when I have a little bit more free time. I appreciate the offer though. 👍
Roger that

In case you need any kind of help, please let me know.
With the amount of effort everyone's put in recently, I suspect we'll have another
20k report month ahead of us. [...] I appreciate the effort from everyone here though, we've probably removed over 5000 posts in the last few days/weeks. That's probably completely underestimating the real amount too.
At the end of December (around Christmas) I had 8032 good reports. Now I have 22.327 and 328 pending to be handled. And on January 1st I had 13.737 good reports. Therefore in the last days we certainly cleaned more than 5000

Yeah, some were active fairly recent [...] I will revisit from time to time though
I also intend to to a double check over all topics after I finish passing through the remaining ones -- just to make sure I reported everything and, in case some are still active (the ones mentioned from December to present could be active) to re-clean them
