Then it lures you in with a "download thesis" tease, with a big DOWNLOAD HERE link. Then it forces you to fill in pages and pages and pages and pages of things that you have no interest in filling. Then it automatically "follows" tons people that you have no interest in following. Then it starts sending annoying e-mails.

Just because you wanted to download that one file, you are suddenly in a "network" you had no interest of entering in the first place.

As one Czech saying goes, "you give then a finger and they bite away your whole hand".
