Pretty much, an addon can only do what the Blizzard API allows it to do.
So it shouldn't be a ToS violation.

Blizzard has in the past, changed what can be accomplished with an addon, by changing their API.
The original Decursive, which would choose the correct decurse to use and choose the correct target as well, merely from spamming the button... comes to mind.

I would assume, Strobe follow is repeated /follow commands, looping every "x" seconds.



Quite a few of us are having the issue with Strobe on.
However, we are not switching strobe during combat.

Basically, run along with a melee toon or several in the team.
Strobe enabled.
Target something, kill it, loot, move on to the next.
With strobe initiating follow after the battle.
Repeat until the collection portion is done.

Out of combat, switch to the next toon.
Enable strobe on the second toon (new jamba master).
Engage in combat again, and suddently the current/new master tries to follow the original master.
Leader was changed, well before the combat -- no one was in combat at the time the leader was switched.
