That's life -- features get used and they get abused too. Where editing is allowed trolls post something controversial and then edit it. Where closing a thread you started is allowed trolls post something controversial and then close the thread before people can respond. Those features are there for other purposes, but trolls use them for their own purposes.
STR might be confusing this general discussion with a specific thread that was closed recently, that I mentioned finding confusing above. That isn't the one that prompted Nordic Viking's question; his question was prompted by another thread in another forum.
Once again, it's not just Platinum Members who can lock a thread they started. That feature is currently enabled for all Gold Members and above so they can close a thread in the Exchange after a knife is sold. That is making things work better in the Exchange.
Hardheart, if the members didn't take any interest in what was going on in a forum, what the moderators were doing and why they're doing it, what kind of forum would that be? Would it be a forum at all?
