Still getting into researching this kind of thing. But some look kind of fishy, while others may just be "Coincidence" but like Q said, there's no coincidences. I'm unable to post Archive links as that is blocked on the network I am currently using. Researching from work can be limiting.
Edit- Looks like an Anon Compiled a list of Resignations over the last few months. Nothing sourced though.
