should we be worried?

that definitely doesn't sound like obren.

We got a website, pretty much the bedrock foundation for proof and legitimacy.  I really see no need to worry, probably some other troll that caught on with the impersonation trend.  Or it's just another crazy fan, either way not much of a problem now than it was before.

They also got the logo for CA wrong ☠️

At least the impersonator credited Vulpine Digital and Obren.

It's most likely some kind of fan-made promotional account, since they didn't do anything malicious or suspicious yet.

The most we can do is reveal that he's a fake in the replies.
