I did a bit of research today and found out that there is indeed a 3rd party Speed hack program being used. (I actually found the program name and where to download it...)
According to the website where its from its been around since 2013.
As far as Speeding your character up it seems the setting on this particular program is "up, down, normal, sprint, max", I'm not sure How they use it but just from reading the information on the site I can get get an idea.
I plan to report this in game to the GMs with the website's link and program name so they can take a look. I hope this issue is fixed by SE soon before the seasons start.
EDIT:
Added a picture of what the program itself looks like, program name removed from the image:
