@Welsh if you agree, I can dig more inside this topic, even earlier than the date of Jan 1st, 2017, but I am afraid that I can have my reports marked as bad if I keep making them. I mean, in case my reports will come to you, I believe you'll mark them as good, but maybe they will arrive in another mod's hand? (I'm saying that thinking that these bad reports where flagged as bad not by you, but by another mod; even so, do you have any idea why they were flagged as bad?) However, in case we can make an agreement, thus just you will take care of this thread, I am more than willing to dig also through the posts made earlier than Jun 9th, 2017, and also earlier than Jan 1st, 2017. Please let me know.
That's probably a better workflow going forward, since that doesn't spam the rest of the moderators report queues, and when reporting just the thread, whoever sees that report can go through the thread, delete what they think is necessary, and then mark the report as handled.
I prefer to handle spam if it's spam, especially if the thread is still active. I do think questions need to be potentially asked what's the best way of handling a thread which has effectively been deleted e.g decent, however I don't feel comfortable just trash canning it since there's a lot of history in that thread which could be of use to someone. I'm thinking potentially archival, and maybe that'll prevent the constant conversations going on currently.
However, to be clear on your question; I think reporting just the original thread, indicating bumping services or accounts have been artificially bumping it would be better, to prevent clogging up other moderators report queues. Then, the moderator handling that report, can either decide to leave it to someone who's willing to go through the thread, and sort it out or they can go through it themselves, and then mark it as handled once completed. At least this way, we're still cleaning up some threads, and also making moderators aware that there's a problematic thread, but it also doesn't clog up other moderators queues that might want to attend to more urgent reports.
Although, I can't really comment on why the moderator might have marked those bad (I haven't always handled your reports in the past, and others have, and marked them good), I do believe some of them were borderline. Some were potentially raising up legitimate concerns, despite the use of profanity. So, a moderator could have seen them as on topic enough. I know I've marked a few of yours bad in the past for reporting content which is basically half on topic, and half sort of abusing each other, but I just lent towards it being on topic enough. Although, some of those posts you've mentioned to me are low quality, and/or off topic, and I would have likely removed at least some of them.
