You think that's spam? Dude, spam is when you say something that is completely irrelevant to anything. I just like foruming. It's pretty much the best way for me to talk to lots of people. Trying to talk to people in-game is very hard, where people can barely notice you if there's a lot of players on the server. So, if people are just gonna keep judging me of how often I post in the forum, it's just gonna make me post more and more until they realize my interest in foruming.
Posting a lot could equal spamming, depending on what you post. Considering you are posting something that is not new or anything, this is spam.
Also, making topics is bad. Unless you have a good reason, don't do it. So, if I made a quality add-on and release it in the Add-on board, that makes sense. Or, if I made a build, and I want C/C, I can post it in Gallery.
