2 BTC got locked, by localbitcoins.com they they unauthorized loging, and require things I can not provide, because we dont have that in our country.
Localbitcoins and Paypal are creepy scammers companies.
I believe that's a totally different issue than the OP's.
It sounds like one of your trades/deposits was flagged for either breaking their TOS, reached the limit that requires KYC/AML or for detected illegal activity.
If there's no reason at all, then you can call it as scam and you can post the info in this board:
