While freedom is cool, bounties and other awfully managed campaigns need to brought in check. Don't ban the concept of avatar/signature campaign, ban the users who cause the shitshow these campaigns bring in. Forum needs a little, just a tad bit more of stricter rules, and I think there'd be a better balance to things than what there currently is.
On a somewhat more serious note: what's prompting you to create this thread, OP?
This is:
https://bitcointalk.org/index.php?topic=5293230.msg55681694#msg55681694It belongs in meta in my opinion as it looks like he's asking the forum admins to prohibit it or make a rule against it.
In that case: What is it with people asking to take away freedoms all the time? This forum gives freedom, enjoy it! There are millions of websites out there that don't give you freedom, don't try to turn Bitcointalk into that direction.
Please!
Maybe it would be a good idea to organize some kind of petition? If enough people agree with this idea, maybe the forum administrators will react and introduce some kind of rule or restriction for bounty campaign organizers.
Here you go.
