So i blocked this guy and now I go to unblock him and a thing pops up saying;

Give it some time!

?

How long has it been since you blocked him?

For some events you have to wait a minute or so between doing things. wait for a few mintues and try again.

There is a delay between how often you can block and/or unblock a person. This is to prevent abuse of the system, as repeatedly blocking/unblocking is against the rules. You'll have to wait awhile until you can unblock them.

o. thanks.
