Blocked/suspended members should write to admin and request him to lift their ban and promise him not to commit the previous mistakes and wait for decision this is the only method which I think is for suspended members.
well in my opinion the person or members who are banned or their accounts are suspended are not be allowed to reactivate their account. Because they are banned due to violation of the rule.
person who is banned may not come back..!! my friend has mailed amny times to the admin.. but admin didnt pardo him
They have to contact admin for reconsideration and lifting of ban. That is the only way I think.
