Nice find! Unfortunately I haven't had time to look through potential connections. I suspect some of the other accounts belong to kotwica666 as well then. I wonder if they're offering an "all-inclusive" signature campaign + paid bumps + shilling service 
I've left dodgrad and kotwica666 negative trust feedback.

Still looking out for more but there is not much tough evidence. Some of the accounts: dodgrad, YuiShuiSiYuan, keyscore44, altcointalk14 seems to be participating in same campaign and registered one after another in some of the bounty campaigns (incl. MYTV chain bounty) but that isn't a tough proof. Naifcopa also seemed to happen quite updated with MYTVchain bounty but he never participated which makes me wonder that he had atleast his alts enrolled in that campaign. While cazkoo I am still looking for but haven't found anything related.
Also the PM that yahoo received indicates that there might be lot going on behind the scenes.
Add them all to signature campaign blacklist- that's the best thing to do atm. I will also drop my feedback on both and continue on with my search for proofs again later.
