Only if they don't mind loosing lawsuits. They've explicitly stated multiboxing was OK.
BTW, I did think about using the follow tool, but not open-source = big red-flags: it's stealing DDO credentials, they're "at war" with SSG and don't want them to be able to easily invalidate their efforts, and/or they don't want someone else to leverage it (for either criminal or other purposes). All of which combines into "hell no".
Removing the EA aura is only a minor nerf in an auto-bot. If you're OK with the effort and risk, there's still warlock and bard TMP HP auras, both of which have more range than the EA aura had. Die hard auto-followers could do MUCH better running a herd of PMs with a negative warlock/bard in the mix. I think the hassle will result in a net loss in both progress and sanity, but heh, YMMV.
SSG would gain so much more from a hire fix than auto-follow nerfs, anyway. ONE new working hire would kill off most of the motivation to suffer the hassle of multiboxing. Auto-match the summoner's level. Support simple hire-play choices: HEAL, melee, ranged, blast, cc, and trap. Voila, hire problem fixed going forward. As a bonus, voice it. A good VA could have a lot of fun there with very little studio time.
Want to make money on that new working hire? Make it the bonus on the new expansion. Sell it in the store as a gold-seal. And, tease it by letting folks use it for free for a week or so (long before the expansion goes on sale .. you want more ultra-pack sales, right?).
Worried people will never buy another hire? Don't be. Make the voice fun enough and people will "collect them all". It's a game. People in general are more than OK with monetizing fun fluff and will happily line up to pay for it.
