He has not logged in to the forum since 4th June 2022 and that really says it all. When people create accounts only to make scam allegations but cannot be bothered to even log back in to reply or to acknowledge those that replied in the thread, then it shows there is no point in any member looking in to the allegation.
Others have posted about scam allegations and stayed the full course until some sort of resolution was found but the OP decided otherwise.
LBC is scam. They arbitrary locking users account and steal all their bitcoins. For most people in this forum my $50,000 Dollar that got stolen by LBC is a ridiculous amount, but for me it was all my savings.
On Redid I read about a person who got stolen 10 BTC.
You got us all confused here! This story doesn't match the story on the video you linked on OP. You said you have $50k on your lbc account (which is not a small amount btw) but the guy on the video has only $800.
In fact, I don't think you are the one who created the video because the guy on the video sounds like a native speaker.
So, please, tell us what happened exactly in your case. Did you upload your own ID, why your documents were rejected, can you post screenshots from your conversation with lbc support? (usually support lets you know why your documents got rejected).
