I actually do side work for a nonprofit that provides free web hosting. At least with my organization, sending an abuse report will get the user’s account suspended until they can look at it. If what they were doing was blatantly illegal (e.g. a phishing site), they just get banned entirely. I’m one of 2 or 3 people who deals with the reports.
On the other side as someone sending reports, I can say that some companies care more than others. I’ve had success getting abuse taken down from 1&1, Hostinger, and Microsoft. That said, I’ve had GoDaddy, Namecheap, Cloudflare, and a few others ignore abuse reports entirely, and I had Weebly actively refuse to remove a phishing site.
My experience is that hosting companies tends to be more responsive than domain registrars at getting abuse removed, if you can figure out who is hosting the content behind the domain. The annoying part is that most just use cloudflare these days to hide the origin.
Even funnier is if you click on the brand SCTOU to see other products, the other items from SCTOU appear to be questionable body armor and anti-bird spikes. Seller names are different as well, but they’re all similar random Chinese names.
