Hello i keep getting suspended and..

Hello, i have been getting suspended, firstly got warned about selling steam games gift with region restriction and i have been warned about it because i didnt type the correct region in the listing and the message was " a region restriction should be added to the listing" and i was okay … but later i have made sure that all my listing seem to be sold in another region and when i added everything in the listing region clearly i got suspended for one month… why me? there is other sellers whose doing same as me for months and they are still on ?
suspend reason was forcing buyers for vpn, mean while i dont do it… i type that the game is sold in that specific region and your account should be in that region, so whats the force in that? need an explanation. because others are same and only me getting suspended.

Hello? why i dont get any answer?
