I likewise have multiple (entirely fraudulent) charges appearing on a credit card for two months now (commencing in January 2009 if I recall), all in the mid-$20's to low $30's. I do not play online games but there is something familiar about the name, perhaps years ago I bought something from them?
As there have been zero indications of fraud on this card, yet I find others posting here HAVE had prior involvement with the firm, and are finding subsequent charges. I wonder if there is a possibility the firm changed hands and the new owners are boosting its revenues by making fraudulent charges based on prior (legitimate) sales accounts? It is also possible that someone harvested my card number in a database theft and it is only coincidence, e.g. someone is using a fraudulent credit card to play. Someone could be doing so to log in as a second user and boost the points of themself as the first user. Ah, we have a new genre! Fraud in virtual reality!
Charges have been disputed, will see what grief I go through for the priveledge of having a Visa card number stolen and used. Sigh.
