The domain name "baba support" has been building up considerable spam pressure against the Stack Exchange sites, as seen in this metasmoke report:
Currently, it shows 78 spam samples, the majority of which have arrived in the last two weeks, at an accelerating rate. The oldest are four months old.
The spam messages are vaguely promoting technical support services, often with what appears to be thinly disguised "answers" to questions which are by and large unrelated (for instance, just now, here's one about Raspberry Pi on an Ubuntu site which gets a "reply" promoting Microsoft Edge support services.)
Baba is not alone; in metasmoke, we have 18 domains currently tagged with #fake-tech-support but the other 17 together have spammed less than this one operation. (Tagging is a relatively new feature and not many of our volunteers are actively updating tags, so this is necessarily an incomplete view.)
As a Stack Exchange user and Charcoal volunteer, I think this needs to be escalated to the service providers whose networks are being used to perpetrate this; very often, the spammers are violating the terms of service of their providers by using spam to drive traffic to their site.
The domain is hosted on 22.214.171.124 which appears to belong to Incero.com so that's where I am planning to complain. I have previously sent a complaint to GoDaddy / Domaincontrol as the DNS hosting appears to be theirs.
Are there any other providers I am missing, and could be getting in touch with?
