I've been moderator in a forum with 100k+ people (gamers).
Not people interested if cryptos. That's much worse than your position in this forum.
I know what you're talking about, I understand you. But still, it's not a good move to restrict such thing. It's nothing bad. Lock/delete existing giveaway topics, clean the mess. It might take you 3 hours, instead of taking you 3 hours per day, every day.
Make a new subforum where we actually can promote things. Where we can bring more people.
I understand that the forum name is 'bitcointalk' and not altcointalk. But there's already a section for alt-coins. Which means we can talk about anything we like ( that's how I see it and more than 90% other people )
You can even make a non post count section for such purpose.
Giveaway KING

I follow you, but what people don't seem to understand, is that Bitcointalk encourages people to go to their own forums, we outright say that this is not the place for your to post every detail about your coin. In the most blunt possible way of saying it, is we want people to go away to their own forums.
This is primarily a Bitcoin forum, that much we are on agreement with. The Alt Currency section was made to be a place to isolate the maybe 100 alt currency threads that there were at the time of creation of the board. It was not designed to handle this much volume, nor did we plan for it, or want it to happen. Everytime someone posts, it adds that post about some Alt Coin that 99.5% of the forums aren't interested in to the recently posted lists etc, so people that are looking for new information about something Bitcoin related on that list are getting drowned out by *insert day old coin name*
Having a giveaway subforum does not help. We don't want to reorganize giveaway threads, we want them to be hosted on forums dedicated to other coins. Its not our job to handle masses and masses of Alt coin information, if someone wants to know more about their own coin, they should go to their own coin's forum. Theres nothing wrong with an announcement thread and a bit of discussion, however with the 600+ Alt coins (that I know of) there really isn't room here, and there is no desire to accomodate it.
If we want to keep the alt coin section at all, we have to make some changes, and we are hoping that removing the giveaway threads will help. We have measures in place to keep the amount of post spam to a minimum, but there are thousands of posts in Alt coin giveaway threads over very short periods of time. Alt Coin giveaway threads are actually the exception, because we wouldn't allow Bitcoin giveaway threads like these anywhere else on the forum. Even the ones in games and rounds pale in comparison.
