One of the more frustrating things in this game is spamming and especially of leqgue noticeboards and guestbooks. Crew limited the guestbook spamming a few years ago but fail to take real action against repeat offenders who disregard this anyhow.
What I ask is can you simply implement that users outside of the country of origin aren't able to post in foreign league noticeboards at all. They have absolutely no reason to besides spamming. Why would someone from another country need to post in a league noticeboard from another country? Fixes the local noticeboards at least but a better solve would be to just completely ban player posts in league noticeboards altogether. If you can do it to guestbooks you can do it to league noticeboards. Onky negative is it might actually require someone to actually do some work and monitor this and uphold the rules that will benefit all the paying users.
The other part of the problem is people then just spam you through instant message but at least you can block those users
