Cheater?

Was checking the competition when I noticed something weird. The 2nd place in my bracket managed to reach tier 18 wave 2762, nothing wrong there, but he only has 60 relics, with one of them being his 2 year anniversary. Maybe it's possible if you play really casually and spend massive bucks, but still felt like checking tower live. When looking up the name I noticed his ID was linked to a slightly different name, pizza2205, but no tournament results were found... Checked several of the other players including myself, everything worked fine so it shouldn't the site flipping out. Thoughts?
