Limit friend requests to eg. 20 per day
Almost every day I get friend requests from "girls" whose profiles consist of nothing but a sexy avatar, maybe a few favourites and an external link. Despite the fact that they have only been members for a few hours, they have accumulated 100's of friends.
It seems pretty obvious that these are all spammers whose activities only detract from the site.
Limiting the number of friend requests that can be made each day would make xHamster much less attractive to spammers and significantly reduce the amount of time you have to spend reviewing Spam Reports
It's been a year since you posted this but it is a great idea. Just like our votes are limited they should also do the same for friend requests. I also feel they should delete accounts that have been flagged by "x" amount of people as spam.
