there is a person on my tl who never comments on my plurks but who clicks like on at least 50% of them

i keep thinking i should remove them because we haven't talked or shared a game in ages, and then... i plurk, and within an hour, they've liked it.

are they just the world's least coordinated plurk muter? are they engaged in a bizarre, silent, months-long attempt to pressure me into paying attention? i just can't tell, and it's starting to skeeve me out.
