Hello everybody.

I recently received a very similar message. First I replied that I wasn't interested in buying additional domains and I didn't want to sell mine.
Their reply stated that if someone registered my Internet Brand, then my domain name (.com) would be "affected". I asked for details, but they (obviously) didn't give any, just repeated that it would be "affected".
The latest email from them included the "price list" of the domains (from 19 to 45 EUR/year) and the internet brand protection (109 EUR/year for a minimum of 10 years).

Below I report the first email:
