I gave up reporting this type of abuse a while ago. Sometimes I noticed that between making the report and it being actioned, pages of further crap had been posted.
Slowly but surely I'm giving up also.
In my case, I also don't even have the time to browse all the topics I would like to read so I only target lately topics opened in the wrong sections or pure garbage ones.
Waging war against is those farms is close to a Sisyphean task or a battle with the hydra, as long as there are stupid "dev teams" or whatever paying for this garbage there will be hundreds of posts and threads bumped.
Probably they will only stop when they realize their topic bumps are not helping the "project" at all.
Check my friends from ECOS for example:

Probably they paid for two months of bumping, the pyramides quotes stopped on the 1 and there is no single legit user posting anything in 10 days
Checking some of them it seems they are unemployed for the time being
