For the moderators:
I just submitted a glitchless run today, but a run from myself 6 years ago is on the leaderboards from when it was ported over from cronikeys.
The old run (https://www.speedrun.com/Portal/run/8m7gkwm0), which isn't linked to an account, could be attached to my account (or removed, since I beat it anyway).
If you need some proof that I'm the same person, you can see that the youtube account that posted that run also posted many of my Bastion PBs which are linked to this speedrun.com account.
It was recently discovered that it is possible to set your mouse sensitivity to a value so high that the game considers it infinite, leading to several new glitchy techniques being discovered.
The rules have now been amended to ban these new techniques in both Inbounds No SLA Legacy and Glitchless.
