I'm waiting for the concert before I run bonus keys, and if I haven't lost track of the time, I've seen the same vendor using 3 different bot accounts to spam within the last 2 hours. Each time the bot stays for 10 seconds or so and leaves. The URLs are the same so it's obviously the same vendor.
If they now have an automated workflow to create new accounts and never use the same account more than one run through the blocks, then we have a serious problem.
It certainly looks like spambots is going to be the defining characteristic of PSO2 Global.
