Don't know if you saw this already:

You're not the only one having problems, it would appear. Should probably confer with those guys as I don't think anyone else on the forum has used Bitshares in approx. 1 million years.

Yes, I saw this post on Reddit and I sent email to hwtu20 (at) protonmail dot com to get in touch few days ago. No reply for the moment.

Also, there is a thread for OpenLedger on the forum, its been inactive for over a year but I referenced this discussion there.

Thank you very much for making this discussion more visible. I sent also request to CoinMarketCap using this form
https://support.coinmarketcap.com/hc/en-us/requests/new?ticket_form_id=360000562051
asking to add the information on the BitShare page about scam risks, but I don't think they will do it.

In the instruction, how to launch a BitShares Cli-Wallet, here
https://dev.bitshares.works/en/master/development/apps/cli_wallet.html
they use an OpenLedger as an example. It looks like BitShares and OpenLedger are affiliated companies.
