Dupe Exploid

Is there a dupe exploid?

I saw a player on my server which sells 200-300 Immortals and server is new and dont have automatic donate yet.

and gms told me he didnt donate.

So is there a dupe exploid or an Silk per hour exploid?

Or your GMs might be, pardon me, fucking assholes and distributing those and other items of which you are not aware.

Check the command history at your database. Other than that, what for files are you using ... that is also important to know.
ecSRO has that bug, that people are able to dupe stuff without great effort.

If you're using old files, such as ecsro or jsro I think yup there is.
When vsro files there is dupe bug also but it only happens when you revoke some permissions from the sql user you're using for the server.
