I know behind the scenes at the code level (or maybe node level) there is a lot of control a developer can have. Is it possible for a corrupt team to make it that only certain people are getting stakes?
You never know, anything is possible in this wild west of crypto.
It would be best to document your investigation first before accusing anyone though. Also check if there is something erroneous on your side of things, talk to other trusted users and see if the same problem is happening on their end as well. These should be your basic groundwork but if your evidence is quite suggestive, then make a thread in "Scam accusations".
Sometimes though, it is possible to take help from the developers (someone older) and sync wallets again, are you sure you have done that?
