I would be very surprised if BitStamp is involved in any shady practices. I'm pretty sure this will be clarified soon.
Have you scanned your computer for malware?
No problem for malware. All is clean. I would be shocked if BItstamp was involved in shady practices. Hopefully, this is just a glitch and will be fixed asap. I informed them they have 24 hrs to explain to myself and have shared this thread with BItstamp themselves.
