This will just make people post more garbage so they can qualify to have ads in their sigs IMO.
My thoughts exactly. It won't work...the more concentrated your posts, the slower your activity rate goes up - but that's not gonna stop the newbs from trying...
First of all, I agree with this change. Second, how would this not work? It's not like you can spam your way through activity levels.
You can. Simply open an (or 10) account(s), and spam as you usually would. (The spam is divided between the accounts so you can increase the activity of all of them efficiently.) Eventually (after about two months) you will qualify for most ads and will be able to spam the forum for pay.
My favorite solution in this thread is to require advertisers to only pay users who make large posts.
It may not get rid of spam completely, but it surely does reduce it a significant amount. The number of people who would do that are most likely less than the people who wouldn't bother. Either way, can't admins just IP ban?
I believe so but not 100% Sure in regards to posting
You can't PM though if in that IP range unless you pay
https://bitcointalk.org/index.php?topic=423995.msg4615746#msg4615746New users can now immediately start posting unless they are using suspicious IPs. Suspicious IPs are ones that have been banned previously, or are known proxies, or are near many banned/proxy IPs. If you register using a suspicious IP, you can use most forum features (watchlist, etc.), but you can't post or send PMs until you pay a small fee. In almost all cases, the fee is less than $1. People proxybanned in this way can also be whitelisted by the usual people who can do whitelisting. These IP bans apply only to registration: you can no longer get caught by random IP bans if you're using an established account.
That said if your ever in a bored mood and want to find spammers the patrol page is there
