> Newegg Chief Legal Officer Lee Cheng says the move is necessary since Minero dismissed its Texas lawsuit without prejudice, meaning it can refile the case at a time of its choosing.

To me this sounds like self justification by the legal staff at Newegg. Most likely the troll is away for good. If they come back at that point engage legally with them. There is a cost to any litigation and this could also backfire. A troll who comes after them and knows that they sue even when a case is backed away from (regardless of prejudice) will be less likely to drop the case at that point.

The other side to this of course is the hope that the troll won't defend the suit so they have bought themselves some insurance. However it's unclear exactly why that matters if the probability of the troll returning is low. Why would they return? Why not just go after an easier target? Newegg has already proven their point.
