link. Initially, 998batrr's username is batrr. Then he changed it, with a 998 in the prefix. Initially, 244mhq's username is mhq. Then he changed it, with a 244 in the prefix. idk what 353cerega's initial name is tho. Kinda suspicious right? Then let's concatenate all the prefixes in their names. What we got is 998244353, which is mind-boggling but this just shows their team spirit even more:)
