After reading this subreddit for awhile there seems to be major issues:
- Coins disappeared from wallets
- Passwords being changed with coins in wallets
- Withdrawal pins being changed
These issue have occurred on every single market that has any decent size user base. Most users blame corrupt admins while the community says they got phished. I suspect its neither. Since it happens on every market almost daily to various individuals across markets and the fact that some users never have this occur at all on any market there is only one solution.
The people having these problems are most likely reusing credentials from marketplaces to forums. In other words they use the same login id and password that for example they used on sheep or the old tormarketplace or wherever. Surely there are admins from those shuttered or active sites that have a whole database of user ids and passwords they go around active markets testing or sold the info. Also using the same credentials on a forum for the market could spell trouble as maybe corrupt moderators have access to only forum passwords and not market passwords and just get bored and try to login and steal.
EDIT: I don't want to say that this is the ONLY way you can be compromised. Phishing and selective scamming admins are always a reality also.
Bottom line never use the same password for anything no matter what closed market or forum NOTHING. And you should change user names also every single time.
Wow, interesting theory! Now we gotta wait for the next user to post about that problem so we can try to get your theory validated.
I think it makes a lot of sense.
