Yesterday I answered this question: Show first 3 lines in html paragraph to find that over an hour later Nikita posted an incorrect and awful quality answer (http://stackoverflow.com/a/15613613/1317805) which was almost instantly marked as the accepted answer.
It seems that yakusha also posted another question which Nikita also answered and despite yakusha's comment this was also almost instantly marked as accepted. A quick Google search seems to return no results for
HTTPFunctions.toMap() so I'm not even sure if this is a real thing.
Considering Nikita has been actively asking questions on SO for 4 months but only started answering (3) questions yesterday, I can only assume yakusha and Nikita are friends or even the same person.
