Interested in Dynamite Jack or Contrast: Collector's Edition? You may try these...

Most ppl turn keys into little puzzle like replacing some letters with ? and then posting something like ? = a for example. Most bots wont be able to get past that.

I myself prefer more involved tricks, like using websites to code key somehow, and explaining how to decode it ;)

So far most fun was website that swaps "words" or "letters" of key in certain way.

Key looks like it should work, and so many ppl didn't read what they need to do before it actually works xD

Forum bots do NOT exist. With the limits on activating keys on steam as well as many humans doing the job faster and more eficiantly they are not practicle.
