-punches Teva economy-
I highly doubt that stopping the sale of elderine scrolls would help stop spamming bots. If you say that the spammers buy their elderine scrolls, they cost ~10s a scroll in Teva. I haven't seen bots around for a while, but in case they're still there, I don't think they have the mind to NPC things for money --> pass the money on to spammer bots --> spammer bots use money to buy elderine scrolls and go to elderine.
Then again, not sure how they get to elderine in the first place. Walking could be an idea, because once you get a bot to the location it's there forever until it gets banned.
