So Instead of wasting time reporting, I simply made the list in the hopes that the managers would see it and decide whether they agreed with me or not.
Definitely, best case your list would get accepted similar to
actmyname's spammers blacklist, where spammers are rejected frequently when applying for signature campaigns.
I've seen campaign managers adding actmyname's list in their rules,
like here by icopress. It's really beneficial for the forum to have campaign managers considering such feedbcks.

I would definitely support campaign managers adding your list as a rule, too.
Mine is limited to active gambling board posters, whereas actmyname covers the entire forum. I believe mine will be useful for managers who are only interested in gambling posts, but that list hasn't been updated in a while because I rarely visit those mega spam threads, and I only read and post in moderated threads with users who are actually gamblers and not just posting for the sake of signature.
Since the majority of the users on my list are still in their various campaigns and are still getting paid, I don't believe my list has had any impact yet; perhaps managers aren't seeing it as frequently because these users aren't tagged (I see it as inappropriate use of the system).
The signature ban hasn't occurred in years; now, it's either you're banned or you're pardoned. The latter is the current trend.
Yes, I'm a bit surprised why temporary bans are "out" after all. A temporary signature ban is rather soft; people can still write posts as usual. It isn't affecting normal discussions at all. I really don't know why this procedure has been abandoned as it's a great way to see if affected accounts should be given a second chance, if they'll contribute to the forum without paid signature or if they are really just here to spam to earn a few sats.
That would entail the moderators compiling a list of temp banned users and monitoring their activities to determine whether they deserve a second chance or not. This is something I doubt the mods would want to get involved in; it's a good idea, but it would add to their workload.
