There are two plausible explanations:
1. Neteller is under court order to hold the funds pending the resolution of any legal actions that are occuring. This would explain the “FBI seized Neteller funds” angle and why there is no further comments. The DOJ/FBI generally dont comment about court actions that are under way.
2. Neteller has the funds in an interest bearing account and are collecting the interest on untold millions of dollars in funds. This could be a significant amount of income and they may view this as a necessary evil to pay for legal defense and to survive the loss of business that has occured as a result of the loss of the US market.
Neither one help us get our money any faster, but both seem believable to me.
