I disagree, I think that the simple past should be "crowdstruck" but the participle should be "crowdstricken", as might apply to someone afflicted by an illness:
"The update wasn't tested, so the servers are all crowdstricken."
Thanks, I added the documentation for this form, and added a second usage note. I initially wanted to tease you by documenting that people with bad taste tried to push for this form, but I really like this illness idea.
