I hope my feeling of relative safety is justified, but I'm not a security expert(?).
PS: Before anyone gets upset that I use such services, I'm not a heavy "pirate" by any measure. When I needed it I purchased software like Adobe Creative Suite or Jetbrain IDE licenses without hesitation. I only use it for things I don't really need and only use once, such as checking out a TV series (I very, very rarely watch anything, relying on specific Youtube and Twitch content instead, leaving two - one came with the apartment rent, one with the Internet - cable TV subscriptions unused).
