Username help

[JuOSu]

I am working on Legacy Score by User and so I am filling in all usernames for players who scored points already. For most of them, that was no issue at all, but I need some help with some that won't show up in search (names are shorter than 4 characters, so search function doesn't work).

If anyone has any idea what users these guys were or how to search for them other than with search function please let me know here or in discord!

S1 WR DJ Law
S2 DE Big Bot
S5 PK Peg Leg
S10 DE Lo Rax

And also S1 WR Josh Garden is under the Admin username, but if memory serves right, that was Ballerstorm?

Thanks for any help
