Weird OSN entries

There has been a username that seems to be blank, not presentable on ranking lists, appearing as an empty line.

Gho$t username appears to be a ghost since there is no clickable record of that id (in ranking lists).
With supa3ek as 2v2 partner they appear on rankings regularly, but without climbing data.
This invisible player has left total of 3 entries on OSN match lists. Impressive since 2v2 team appeared first time on arranged team ranking list on 2013-08-30.

If your name consists of emoticons it will appear blank on the rankings.

Ok. Mystery solved.
Team appears as a new entry on every ranking list, too.
Also it looks to me that match is not recorded as an replay either.
