Unless there are other cases that I missed, then if I am not mistaken, all of it are kinda solved. This post of mine on other thread gave a brief summary, and that was a bit behind the latest update.

Up to this day, user from case number 1 was never be seen anymore, with last post on the thread made by themselves, at 30th of May, and their last online date was more than one week ago as per when this post is made. Not sure if the silence is because they escalated the case to the EU authorities like they said they will, they waited for a response, or something else happened. So, it's actually 50-50. One might argue the user left the case because they tried their luck of playing victim and lose, while other might argue their silence is because they're working in the background. So, taking assumption of the later, let's say it's open.

As for case number 2, Rollbit and the user finally took their case to the licensor. Though the case should be still in early phase and perhaps currently being reviewed by the licensor, given the verdict made by CEG is binding to the parties involved and final, it is as good as closed.

So, to summarize and reflect to the latest situation, accusations about Rollbit are as follows:
1. Rollbit - scam 5k - GDPR PROBLEM
2. Rollbit disables account and seizes funds (10.2k)! - pending for CEG's decision
3. Community Warning - Rollbit ⚠️
4. Rollbit hold funds and ignore in chat
5. scam warning rollbit.com banned my account
6. rollbit scam (255 USDT)

And of course, as you also noticed and well mentioned, this one is not Rollbit's case, and rather an impersonator.

Where are these plenty of complaints?
