I believe once you like it stays there even if you unlike, for the views I think it could go up even with one person because one of my series has about 534 (today was about 51) and most of the time I am going into my series and the count for views goes up, I wish it didn't though so it could be that but if it was true then the dedication to do that though is weird
Edit: I don't remeber going into my series 51 times today...
