Nothing that I have reported can ever be confirmed as I am never told the outcome of a ticket.
Though I believe it's working as after a few days from when my tickets have been actioned I cannot locate those reported in the armory or see them online again :)
The below notes are for anyone who wishes to spend some time cleaning up their realm of these unwanted individuals. And this can be done while being in your capital city! ... no need to follow anyone or move to a particular zone.
Step 1 - do a /who Uldum
Uldum is popular for Mining and Herbing ... particularly more mining. Depending on your realm you may see a few people there, or many.
Take note of any level 80, 81 or 82 character in that zone - the reason I do this is because quest only begin in this zone for level 83+
Add all these characters (lvl 80,81,82) to your friends list, and if they're in the Uldum zone for more than 1 day continously and fit the description of what I'll explain below I report them.
Worth noting is - that because tickets may take a few days to be actioned you may notice them to be in that zone for days. Whenever you log in they are there, and while I could not prove they remained online 24hrs per day, it did appear this way.
What else I have noticed is these have all been SoR characters. Evident from wearing either the Zeolot or Windsoul gear. And evident from their recent activity when your armory them as they have recently earned all the exploration achievements, along with the level 80 achievement etc
They will also only have one profession learnt - either mining or herbalism. In most of my reports so far Paladin's are miners, and Druid's are herbalist.
They will also have no enchants, no glyphs, no gems, and even some unspent talent poiints.
After a few weeks I'm noticing patterns which I'm sure internal Blizzard staff are aware of ... but the above is the most simplist method initially of detecting these.
I don't want to explain how to do this for other zones, or levels 83+ as it gets more detailed which will make this post too elaborate ... but if you find doing the above rewarding even if it can be a small time sink I'm sure you will start to notice things :)
