> ThreatExchange (aka TX or TE) is used by multiple companies to share signals on a variety of topics intended to prevent real world harm. Some examples of how TX is currently used include sharing malware, phishing scams, and terrorism signals with the goal of helping all participating organizations tackle these problems based on their terms of service.
I think it is simply the domain name itself, not anything they did. The domain name he uses (stamhoofd) translates to "head of the tribe/tribal leader". I can imagine that such a word can easily have bad connotations and nobody wants their brand to support any site with a potentially offensive name that can turn into a PR nightmare. Likely it got flagged for this reason.
Good question! I would also like to know the answer. I've scanned through our sites and couldn't find any malicious content... My guess is that the block was automated, and might have been caused by a fake spam report. There can be some competition between non-profits (e.g. two scouting groups in the same local area). Maybe they started to report each other as a joke.
Did you consider the fact that your domain name itself could have been the cause by itself? It is not extremely far fetched that stamhoofd could somehow find its way in being found offensive by some automated tool (or a person who takes these things very seriously). It would explain the TOS violation too, if it considered the word to be problematic.
Right, from a user's point of view labelling it "Spam" has the same effect as when you put letters unread on that pile by the door, "I don't want to read this". Should they? Doesn't matter. Years back we even had users who were paying us to send them specific emails and would mark it as spam.
The use of "users marked this as spam" as a signal is a cheap but lousy shortcut and it's bad news that we became reliant upon it.
