@standev @mvilain @jerry That's propably because of that.

• I know companies that'll instantly block any domain registered or adminitrated or linked to #GoDaddy, #NameCheap, #NiceNIc, #CloudFlare or #ProtonMail due to rampant #spam, #scams and abuse by #CyberCrime groups.

In fact I did that - alongside #Geoblocking - to prevent and deter #carding attempts at a fmr. employer.

• And like many modern sites, attempts of registering an account would just get #blackholed without any notification and said IPs [the entire block allocation as per WHOIS!] temporarily blocklisted for 24 hours.

Granted this wasn't my decision but basically what the CLO & CFO saw fit as "cybersecurity and risk avoidance strategy" towards regulatory pressure by @bsi & @BaFin ...
