I'll be replying from my own knowledge in networking, not representing GMs in any way.
If someone is smart enough to use certain services to bypass region blocks then good for them, it's just the very minute any abusers (zenny sellers and others) end up using the same service then that service's IP range will also get blocked :S
Of course they won't have proof on the nationality of the person himself, but they do have proofs of from where the person is playing.
It's sad to see it has come to the point of banning regions, but this isn't the first time I see whole regions get blocked from a certain service because of increased abusing coming from that region, yes it's an unfortunate side effect that regular users from the same region get blocked but this is the way I've seen it done in different places.
I noticed there are people who think they're behind some big shield of anonymity that they admitted they use bots, had to ban those from forum. Also talking about bypassing services in detail is kind of sensitive in MENA so I'll have to edit some posts in here.
we have got the answer thank you Mr. cypher !!!!!!!!!!!
