I totally understand the forum mission to be "as free as possible" but there is a fine balance between "free as possible" and pass the feeling to the community that something is always being done to prevent this escalate of douple-triple post users and spammer one line posts (while keeping the forum motto true to its roots).
I'm all for free speech and freedom to post anything you like, and have defended both on multiple occasions on these forums, but I draw a line when your posts start affecting other users' ability to actually use the forum for discussion. We don't need any new rules or restrictions to clean up this mess, but rather we just need to enforce the ones we already have.
Interesting you should reference this post:
When barriers to participation are too high, then the best people often just won't go to the trouble of joining, and the people who are willing to jump through the hoops are often people who aren't good for the community: people with nothing better to do, scammers, get-rick-quickers, etc.
Is that not the situation we find ourselves in more and more? The barrier to participation at the moment is wading through pages and pages of spam to find a topic worth reading. The best people aren't going to go to the trouble of doing this, they'll just find a less spammy community. The people who are willing to wade through pages and pages of spam are the spammers themselves who are only here to try to make a quick buck.
