I wonder if those "ICO managers" or whatever they're called (the ones who create ANN threads on behalf of various shitcoins) could abuse this.
E.g. wait for your competitor to bump their thread and then bump 50 of your threads immediately, knowing that the competitor can't do anything about it for the next 24h.
Come to think of it, just create 500 dummy ICOs and bump anyone you don't like off the front page. Much harder to do that when there is a more tangible cost, like a merit.
Underhand tactics in business who would of thought? Yeah, this could be abused by opening several threads, but maybe there could be restrictions to who can open threads in that section. Any of the higher ranked members caught doing this could be temp banned, and maybe permanently if they continue to do so. Its spam after all. I hate restrictions usually, but most of the solutions without any sort of restrictions will be abused, and unfortunately we haven't got enough manpower to actually recognize every single one. If someone is opening several threads, and bumping it then its definitely clear what their intentions are though.
We have to weigh up the options of imposing restrictions, and allowing spam. A restriction such as certain rank+ only able to open threads to prevent users not caring about registering hundreds of newbie accounts, and being hard to identify who is behind it. Maybe, copper membership. Yeah, its putting something behind a paywall which I'm also usually against, but there has got to be compromises somewhere for the betterment of the forum, because quite frankly in its current state the altcoin section is very hard to view.
