I got a response from the official team behind the actual service:
Are you aware of the spamming related to a supposed promotion posing as "margin bot"?
The spammers are using your intellectual property, including your name and logo as well as a 1 to 1 copy of margin.de in a different domain. I don't know if those operations are linked to the original service (the one here) but they're using a domain registered on 2018-04-05 which I couldn't find to have any connection to the legitimate service here. Could probably be an attempt to get users to download malicious software.
Here's my documentation of this:

Thanks for reporting this! We reported them to the moderators. We would appreciate if other would, too!
All the best,

I think we can say with certainty that this is an attempt to spread malware!
I've PMed Theymos so hopefully we'll see this addressed soon.
