my thoughts(shacknews name is unleashed)
Given that there really aren't rules on how voting takes place I'm begrudgingly inclined to not disqualify either(and lets face it, its not like we haven't seen the chatty attempt to sway an external competition or two before). Imho as long as the votes are tied to unique ip's, they stand as is.
That said I think #1 is pretty blatantly obvious, and #2 irks me because an entry for the jam should be available to download via itch & ads should not be in a jam entry either(this should be a rule for future jams).
That said, I think for JamV, in addition to the two choice awards you keep the itch vote(or you could make a chatty only vote) for a third community winner which gets a shiny chatty badge(and no monetary awards). id also be inclined to have community badge awards for the other two choice awards too.
