This is something a friend always talks about, and I totally agree with him.
My mail is full of friend requests. I don't delete them so these stupid people who randomly invite anyone at haven can't send me a friend/guild request again.
Some (stupid) people walk around haven shooting invites randomly(maybe not totally random) at others.
Why? Because it's free, why not? But wait, what if it wasn't?
Then these (stupid) people would stop doing it.
Why stop?
Because most of them are noobs who only want free money in the first place, they can't afford spending what little they got on friend requests.
I'm thinking 100 to 1,000 crowns would be a good range. Or could be 25 same as mails.
If you really want to be friends with someone, they I think you will be willing to spend that much(it's little, really). If you think it's a lot then that's not someone you really want as a friend. Yes, I hate fake friends.
An Ignore option is there for a reason, you know?
