As is the case with shitposts, what spam is can't be determined by whether it generates fun or not. It's possible to have fun with anything that exists so that's not useful. I think spam, putting aside the traditional meaning of unsolicited adverts, phishing, malware, etc, is about disruption. Not disruption through derailment like a shitpost, but something that lessens the interactivity available to the user, by for example filling up a platform with meaningless messages.
I also enjoyed riding the waves, it was nice. But here it'd be a shot in the foot, and that's part of why it was unique.
it's only spam if I don't like it
Hmm. Interesting bug. The cross-board links got turned to plaintext every other one.
sometimes everyone on /qa/ having the same sleep cycle is problematic…
