I strongly dislike people who (I feel) abuse the legal system. My typical response to threats to sue for defamation is to refuse, and perhaps publish even more negative information about that party in response.

(My two brushes with the risk so far have been my TCG-Con article where they threatened to sue me and never followed through, and my tangential involvement with the vexatious litigant Oliver Smith; I offered to host on my website one of the articles that he kept trying to get taken down via legal threats, but ended up not doing this because it stayed up elsewhere.)

This has not caused any problems for me so far, and nobody has ever actually sued me. However, that may not remain the case forever.

I will include for this purposes of this market suits that are technically not "for defamation", but are clearly in response to me publishing information that the other party did not like. I will also include things that may not technically be "lawsuits" per se, but de facto are, such as BC's Civil Resolution Tribunal.

(If someone wants to sue me to manipulate this market, I guess go for it. I'm not going to add a rule for that.)
