In one of the even more absurd cases: According to an AP report (cited in Slashdot), Intentia International has filed criminal charges against Reuters PLC, alleging that the news service illegally obtained an earnings report that the company had not yet released, by guessing the URL at which it had been posted on Intentia’s public web site. Intentia claims that the report was “not available through normal channels,” according to AP. (Also see Financial Times and CNET News.com reports.) DES
I was accused some years ago (like… 2012?) of “hacking” an alpha of an online game because I changed some urls to get items or move them between players… I actually documented all of this and sent them plenty of bug reports. It was an alpha, after all and we were specifically asked to report bugs.
They then literally sent me an email and told them that they can see my provider from my IP and will contact them to sue me for hacking…
The game never left their alpha state and soon after closed down completely over some drama where a mod got access to important keys and locked everyone out.
Fun fact: the programmer of that pile of shit then announced that they started working for a huge online game company.
