Currently there is a thread prefix called [L33t/Ub3r] in the Freebies/Giveaway section. However choosing this option does not really make a difference, and regular members can still post on the thread which in most cases will just make it harder for OP to give away the free stuff, since they need to sort regular members who dont understand this.

My solution is that all [L33t/Ub3r] marked threads will be restricted to this specific usergroup and maybe some sort of post to view content system on these threads to increase the forum activity and still filter the spammers etc.

It's really not that hard to just scroll past regular members in those threads. Additionally, those members could still PM the thread author if this were implemented.

and maybe some sort of post to view content system on these threads to increase the forum activity and still filter the spammers etc.

That's just asking for low quality posts.
