First of all, I quite like the idea that I can earn some money on the side while doing something that I intended on doing anyway, because I enjoy it. I probably posted a lot more when I wasn't in a signature campaign years ago, naturally I've become a little more busy as time progresses, and you could probably say I've matured a little more, and aren't quite as excited as I was before to get involved in discussions.
Though, I still have a passion for the forum unlike any other I've encountered. Some might think that the moderator position effects my attitude towards signature campaigns, but I don't think so. I love the mod position, and I also love earning while doing something I would do anyway; post. I think it's natural at times to be more motivated to post when your earning from it, I won't deny that's obviously a motivation for a lot of users, but if the content is good, I say let it be, and not worry too much about the motivation behind it.
I literally don't participate in any other forum, and I think that speaks a lot for the quality of content available here. Yeah, the forum has its problems, but what doesn't have its problems these days. Bitcoin something we're all here for, has its problems.
I'm also someone that struggles to pick up new habits, for example I've been introduced to several other ways of communicating about Bitcoin, and other interests, but they never really stick. The forum has, and I'm going on eight years now since I've registered. I definitely haven't been in a signature campaign for that amount of time, so yeah I would definitely be still here.
Although, I do concede that this forum would likely lose a lot of traffic, and I have no way of verifying that, but it does seem a lot of users come here with the prospect of making money either through altcoins or through Bitcoin signature campaigns, which I'm totally fine with.
There are still few (as I know) who do not wear signatures even though they can easily wear and get accepted everywhere. They are the real ones who would like the signature free forum.
I think there's likely quite a few users here who would prefer a signature free forum, but while its not they might as well earn a little something on the side. I don't really have too many complaints about users using it like this.
