What we really need is a reboot of USENET in some magical way where there's no incentive to spam + micro nonzero cost to give them a reason not to, something like 100 posts for $0.01.
The reality is you'll get weird spam posts even if you block links with just basically garbage text just because people can. So add an irrelevant cost to put it above zero.
Here's an example of the spam for no reason: I've got a vintage site for a project http://bootstra386.com with a vintage guestbook. Instead of filtering out spam, I filter it over to something I called spambook so you can feast on the glory of all the spam bots postings - it's so excessive and ridiculous - actually I think it's just erroring out from too much memory now. I'll fix it in a bit
