It seems like it could be slightly counter-productive to place priority on restoring the accounts if the issue hasn't been successfully resolved yet. We all know that Frogster has the means with which to restore your accounts/items/gold, so on and so forth is all in their database/records/logs (as long as they don't wait x-amount of months after the fact). I don't see any rush to get back into the game if you've been hacked once and the risk still exists.
I see Support doing a few things here.. 1) they're temp suspending affected accounts, which I assume is for your benefit and security to prevent further damage, 2) they're investigating the issue, which will take some time, 3) once they find the cause of the issue (maybe they have already?) they then have to fix it which may or may not require the involvement of more than one department. The time of the last point is influenced by the cooperation/speed of department responses as well as the time to implement the actual fix. Needless to say that's all assuming that the issue is even on Frogster's end, as we haven't 100% confirmed that this is or is not the case.
Players should stress to friends and guild members how important it is to contact Support *directly* if they are hacked. I agree with the staff 100% on this point. Contacting Support on someone else's behalf is a limited gesture of assistance. Support won't be able to get all the information they need regarding the incident from a 2nd-hand source. It's probably acceptable to report a player's name, the server, the time/date, and a SS if possible if you see them being hacked (like being a good neighbor), but there isn't anything more you can do beyond that. If you know the player personally, get in touch with them ASAP, and have them take the necessary steps personally.
