It's sad to hear what has happened, brother. Well, any online freelance platform will take the customer’s side not the other way around. I have lessons learned but not hard punch like yours.
Try to send a cold message to 5 -10 your previous clients who know you very well and have a mutual understanding between both. Saying you would love to work with them if they have work for you etc..make a convincing story but acceptable.
Hopefully if they give you a job with 5 star rank you have a chance to get back on the road.
Cheers bro..🤞
