So it is circa €1.200 monthly for printing and sending letters? isn't it? So who is still expecting to be legal business?
Nevertheless, I am curious af about the content and purpose of the letters now (not as a criminal, but as a lawyer...).
If you need a printer, these will probably be offers that are definitely associated with investing in something very risky or simply a scam
I'm curious about the targets too. This may have something to do with GDPR violation, using personal data of big potential investors. Anyway, if it was already tagged as scam in the German local board, it doesn't look good at all.
