I bloody hate when on YouTube people at the start of the video beg for a like and a subscribe, fuck sake, show me the video and if it's good I'll do it, begging for it will just make me NOT doing this
I also don't like the "content for you" features, let me pick what I like... I don't use Twitter really but Facebook does the same, some pages get shadowed because they are not aligned so you think they are dead when they are not...
At least on hive there's no algo besides hide low reputations comments or posts, but not even in all front ends
