Aloha,
As stated above most of the time you can look at their turret orientation and you will know if they EVER connected. If all turrets are centerlined and not repositioned they never connected and it's not technically an AFK, they could have crashed etc.
Currently A LOT of ISP's are having equipment issues, case in point I know for a fact that Comcast has an L1 switch down in the western states and AT&T has a switch down in the east whatever part handles Georgia specifically). Due to the higher than normal traffic on all ISP's some are getting more frequent disconnects and crashes.
Also, remember that WoT and WoWS are two totally different development teams, so A LOT of the features they have do not translate over.
Mahalo,
