The manager should not be accepting spammers in the first place. I don't have time to do their job for them for free (busy enough with ChipMixer as it is), and even if I wanted to do their job, there's no spreadsheet with a list of participants.
You sound like too much biased into the past. Please remember this forum got enough active moderators to catch and punish spammers as per mentioned
here.
You are always welcome to check post history of anyone from this forum and to report accordingly. When you got all the opportunity to fight against the spam, it is leading to think "something different" when you are TOO MUCH BOTHERED about spreadsheet. In short, you want to fight against spammers just after this campaign ?
Forget the past, wake up for present and catch the spammers.
But, before that explain what is spam and guide in more elaborated way. Because, I guess this is not enough nor appropriate to understand to bring changes to writing contents.
Spam is "irrelevant or inappropriate messages sent on the Internet to a large number of recipients".
