I've quit trying to play ETH blockchain detective and have been misled by people's evidence in the past, based on my own ignorance.  If a trusted member can vouch for the connections you've made, I'll happily tag these guys. 

It could very well be possible they're connected and all in the same bounty--but you know exactly what they'll say:  "We're in a team/family, we're all part of the same network", etc., meaning they're on a shitposting farm wearing straw hats and more teeth than words they know in English (though I have not yet looked at their posts; I'm just projecting the outcome based on previous outcomes of situations like this).
