Monitoring addon traffic I am seeing astral keys send for example:

"sync5 CharacterName-Realm:MONK:375:18:0:221:2_CharacterName-Realm:HUNTER:377:19:19:221:447426_CharacterName-Realm:SHAMAN:377:20:17:221:394720_CharacterName-Realm:ROGUE:380:19:17:221:390842_CharacterName-Realm:DRUID:381:18:16:221:379500_CharacterName-Realm:WARR"

Example might be off a little bit because of character names redacted, but the message is 255 characters long but as you can see the one character is cut off(addon message limit), I think this is causing some characters to not always be properly tracked. Looks like its trying to send 6 characters maybe reduce it to 5 or even 4 considering the character names in the real data where not even the max character + realm name length so messages could be even longer and therefore cut off even more.

I am also seeing that other people are reporting my character back to me. After a request.

Is this still occurring?

it was. I have since wrote my own key addon. But as far as I know this is till occurring.
