Project mention: We Spent $20 to Achieve RCE and Accidentally Became the Admins of .MOBI | news.ycombinator.com | 2024-09-11
A friend of mine recently let the domain used for documentation of Pykka, a Python actor library, expire. Some of course registered the domain, resurected the content and injected ads/spam/SEO junk.
Since the documentation is Apache License 2.0 there isn't much one can do, other than complain to the hosting about misuse of the project name/branding. But so far we haven't heard back from the hosting provider's abuse contact point (https://github.com/jodal/pykka/issues/216 if anyone is interested).
