i bought upvotes in the beginning like 2 times and then i realized they dont make people see my content anyway, i did it more for people to notice me,idk it's kinda what you are talking about but hey i like to see people notice me :D
But hey i wasn't noticed and i didn't saw a point in that(buying the upvotes) but for example minnow booster who gives free upvote what i have started to use lately is more of a (hey easy money :D not a lot but i am grateful anyways) and i also met new people on their discord so that is good :)

But i dont get the constant buying of upvotes, i mean i like to see actual people see my content, which also goes for followers, for example for me i posted and got 20 new followers in 1 minute, totally legit :D
