If this is the reason then why admins are taking 2-3 months to resolve someone's issue if they have valid proof of ownership and if they had thousands of pending case due to this then they should find a solution to the problem.
1.Recovering Lost Accounts is forum's least priority.
2.It becomes ever tougher if you're not a known good contributor to the community.I have seen people with good trusts and rep getting their accounts recovered faster.
3.That doesn't mean the accounts can never be recovered,takes time,even months.All you can do its send admins the proof they want as mentioned in the stickies and send them monthly reminders.
Its not so fast and monthsto recovery its a not normal position here.In that case ,would be only one here.Ppl look and read threads about same problems,see how its going and what a real position from admins to solve their problems here and go out or start be quit.Last two years is show that trend here,better than tons of posts.Its not have any sense who are make a security error at first ,at first here a problem with login that have a normal good users (Im was hacked two weeksa ago and what status Legendary,+60 trust points,few active topics ,that must be updated,given all rthatneeds to recovery to admins,sign message from associated address,confirming my ownership to myaccount from another members of forum ,includes exchanges and what? Im doing all that needs to not be hacked and how im getting that im not understand,and why my account not back to me im not inderstand too) ,no feedback,itslooks likeignoring ,because not to see my threads and PM's its impossible,ignoring its possible reset email address or passphrase its maximum can take fewe minutes by admins ,but ppl must wait months for getting back accounts and already if asll known about that forum was hacked in 2015 why its cannot behacked in 2017z? Three year im here,its cost anything to admins , what feedback from community they want to get if they are shown same position to the problems of community members ,which can be solved only by administrators level of access?
