Yes thats right. If you have an old blockchain wallet account that keeps asking you for a second password (although you never had any) to let you log in and denies you access every time you put any; I can help you access that account if you still have the correct password and know the email address you registered with; You can come to me for help only if you are 200% helpless and clueless and are 200% sure that you can't get help from blockchain.com support or anyone that you know. I can be your last resort and I will help you have access to the account but for that I will charge you 50% of whats inside the account. I can prove myself to you if you can provide me any dummy account prior to accessing the one in question.
I don't know if you are going to be very successful in getting people for what you propose. First of all, because we have no guarantee that you are going to get it, other than you say you can do it. But secondly, and more importantly, in the event that you manage to regain access to those funds, what guarantee do I have that you are not going to keep that money and give me half of it?
If you were someone with a great reputation in the forum, maybe it would be more credible, but a newbie does not inspire much confidence with this proposal.
