But most password programs do this too, if you install the plugin (which you pretty much need if you want those same programs to do the passkey thing, anyways)
Popular gaming forums NeoGaf and Resetera only allow signups from paid email accounts. All free and temporary email providers are banned to discourage trolls / forum raids / alt accounts.
I have been "permanently" banned for embarrassing some abusive moderators; now it has become a vendetta. I'm not sure how many user-identifying methods they attempt, but it overcomes VPN usage. I obfuscate my Web traffic now and it seems to have foiled these losers.
You don't have to be charged with anything to be arrested. Kennedy's wikipedia page suggests they were released from jail, implying LEO decided they actually committed no crime (and certainly weren't charged). If you're really curious, maybe the jurisdiction has public arrest records, but this assumes that the cops were doing everything by the book, which is not always an apt assumption.
My guess is that towns and leo get, let's say, passionate, when a big tourism draw gets defaced, or when something can get more dangerous, but cooler heads eventually prevailed.
There are usually separate categories based on various factors, like which console a game is played on (if it was released on multiple), what the win condition is (do you need to 100% the game, or just see the credits roll?), and whether certain glitches are allowed. Those are nearly always software glitches, but hardware glitches aren't unheard of :)
Speedrunning communities generally hate it when having more money leads to an advantage.
If you ban deliberately smudging/scratching the disc, then some runner with a lot of money will just buy a lot of copies of the disc, find the one that glitches the most consistently (because of pre-existing scratches, or even manufacturing defects that aren’t visible)
Allowing some kind of mod is the most equitable compromise.
They typically ban the glitch entirely. For example cartridge manipulation or "CD streaming" glitches in Zelda speedruns are banned, and if you submitted a run containing them while claiming the game did it on its own, they would probably tell you to get a new copy of the game.
Also since the service does not store your private key, it is more resistant to data-breaches as that is one less potential breach source.
