You can see who gives you rep.
You can go into the paid member forum. With that, you can negative rep spammers in the bin to clear your rep limit. There's also the Edge, which is clearly NWS.
It's only $30 and it's good for a year. :p
how come i can never neg rep the spammers, it always still gives me the 24 hour message? how do you do it scar?
When you get the 24-hour limit, wait 24 hours. :p
When you negative rep spammers and max out for a day, you should be able to rep someone without that "You must spread rep around..." that you repped just recently.
