I don't get your point, do you want to actually deter real players from entering and giving the company 10$ for doing so?
Are you aware you can have bulk accounts from abandonned botfarms for as low as 30 cents an account?
They never buy directly spellbooks, there is actually so much second hand accounts for sale in bulk for peanuts, strictly no reason to do so.

The only thing you'll achieve with this is putting a huge barrier of entry to the people you want to see coming in, while botfarms will laugh all the way because you closed a door they never use in the first place.

Also, a new botfarm would never open at 10$ an account, it would take them years after years to roi on that.

I'm sorry i'm voting against, there are already few enough spellbooks sold to real player to not make the wall three time higher for them. You want them all inside the disco, not out at the door with a too expensive ticket.

If you pay 100k DEC to get that out, you're basically going to loose money, to loose even more money on your SPS stack as it will be detrimental to the game in general.

Hope you get my point.

TLDR : Bots never buy spellbooks.

Just as an example, on the Xbot page, which is already expensive stuff but still 10x lower than company spellbook : https://xbot.app/discountedAccounts
