These spam threads aren't "forum discussion". They aren't designed to promote or invite discussion. They are meant for a small group of people to fuck around in. This would be ignored if you were doing it in one big thread, but instead you're doing it in more and more and more threads. You say it's not harming anyone, you say it's not douchey, you say the people who criticize this trash are the douchebags.
"Not harming anyone". I mean, not in a big way, but it might be harmful to the user experience when someone is browsing the forums and there's 10 threads full of inside joke bullshit that probably SHOULD be kept to skype. These don't seem appropriate for a public forum, they don't invite discussion from anyone other than the small group of people who keep posting them. I honestly agree with the idea of just having one big thread with this stuff. Otherwise it just seems inconsiderate to the other forum users.
You guys are intentionally pushing further and further to see how far you can get, and when you get criticized you whine. Why must you be so unreasonable? Why must you intentionally bother people so much? Don't act like it's not intentional. There's no way you'd keep making empty pointless spam threads if it weren't the case. Fuck off, idiots.
