These two players are of similar levels, joined Warlight one day apart from each other, use the same blank username and have similar-looking profile pictures.
They both used to appear as if they were from Germany, but when people started noticing, one of the profiles' location mysteriously changed to Romania. When this happened, ANOTHER user with no username commented:
So they hop between Romania and Germany to take their turn, do they?
This user was level 2, and had no profile picture. Considering that this username was also blank, like the other two, this suggests that this account is yet another alt, created to point out the changed location of one of the accounts in question. It can, therefore, be safely assumed that a proxy/VPN was used to change an IP address.
And yet another thing: the fact that these users have no usernames makes it impossible to click on their names to find their profiles and blacklist/report them. Given the earlier-mentioned reasons, it would appear that this side-effect of a blank username was intentional, solidifying the argument that these two accounts are being used by the same person.
Verdict (or tl;dr): These players are almost certainly cheating bastards. Blacklist them.
