Pretty self explanatory.
I report atleast 5 people a week for posting retarded, useless comments like "haha nice", "Cool, will try", "Awesome, +rep" repeatedly in every thread so they can to boost their post count to 50 -- usually within an hour or two.
Sure they get their posts removed and a 1-week site ban, but that's just the few that happen to spam their crap in one of my subscribed threads. I'm sure there are a LOT more leechers with 50 posts out there just hunting that forum.
Some leechers just go down every single page of the account giveaway section to join in the contest or snag the acct info. Rarely do they +rep anyway for what they receive. I even have people posting in my month old thread about an account that I said several times was already given away to Krazzee. People just don't even read. They read what they have to do and PM me for the account or post or w/e.
Make a rep requirement on that section. 50 posts just provokes spam. 5 rep wouldn't be enough because they would just all rep trade eachother. My suggestion would be 20 or more rep. This would eliminate more of the true leechers, and maybe inspire even more people to actually do something productive that contributes on the site. Because really, if you havn't even read any of the other sections or posted your own exploit or program or guide or ME or w/e -- you really don't need or deserve a free account as it is.
