Also, it means we can have more 'spammy' posts / more games without worrying about it getting deleted for spam.
Not that it's a bad idea, but I think we can safely assume signature ad spammers would start shitting in other boards, because they only care about their bottom line — the level of their monthly payouts.
Well, at least if they're posting in other threads, we can report their shit as spam and they get banned. You can't really report posts as "spam" when it's technically on-topic but non-productive.
I don't know, it just is rather annoying to see hundreds of non-productive posts a day. I mean, you shouldn't post just to earn money via your signature campaign. You should post because you're contributing to the conversation or creating entertainment for others.
