[2] Report: what rule(s) they broke (quote them).
Section 5 - Hacking/Exploits
#1 Hacked Clients [or Modified Clients]
All types of modified clients, that deviate gameplay functionally in any way from the original Terraria client; this also includes using 3rd party programs, such as Inventory Editors, to modify your character to possess impossibilities, but texture packs are exempt*. Warnings may be given, however due to the nature of the people using these clients, warnings may not be required, and in cases where this affects other players in a negative way, to a degree of selfishness, then the ban may not be appealed.
[3] Did this affect anyone (e.g. they were using their hacks in PvP)?
They used a modified client (seemingly a speed cheat) that allowed them to gain an advantage over other players within the PvE dimension.
[4] Evidence. (If this includes chat, Phase link one or more messages)
