To address several points in no particular order:
Porsche warranty exclusion is a matter of contract law. Read the contract as chows suggested.
I expect PCNA to warranty my GT4 for non-racing track events (e.g., DE) since it is clearly marketed and built as a track car (but not as a race car) e.g. TPMS race circuit setting, numerous marketing pieces, the EVO interview with AP, references in the owner's manual.
Insurance Coverage: read the myriad threads on that subject. It too is a matter of contract law. Read your policy. If the language does not exclude DEs (i.e., any claim arising on a race track or similar language) you're covered. Most, but not all, exclude.
PCA DEs officially prohibit/discourage timing as a requirement of PCA's insurance.
DEs are quasi-public venues so there's nothing to prohibit posting track videos or still photos (as is common by track photogs trying to sell to drivers). As said, it's really bad form to post crashes unless you are the involved driver or have the drivers' permission. That said, there's nothing to stop it other than peer pressure or the event admins. In my Region, we don't regularly have car damage, but when we do we call a drivers' meeting to reinforce our morning caution. We police the crowd that always gathers to gawk. We've never spotted any unauthorized posted incidents, but if we do I expect we'll take some action against the poster. Perhaps a ban from future events. DEs are already threatened without idiots creating the illusion of track carnage.
