<p>From asking other mappers - it seems that ongoing porn/scam site spam attack is not sophisticated, link to <code>https://go.cm-trk4.com/</code> domain seems shared by spam PMs.</p>
<p>Maybe starting from blacklist of terms that would vastly increase consumption PM quota would be viable start? Blacklist will fail against sophisticated spam attacks, but this one seems to not be come complicated one, they are not even using domain pool.</p>
