Is there a purpose to shop ids

[Rudol Von Stroheim]

Is there?

Seems like risky stuff that has minimal purpose as far as I can tell? I did the simple PTR tester shop id on a lvl 1 account and it requires the badge. I then found out that there was a packet spammer to get it but the packet doesn't work anymore. So is stuff like that the only purpose the shop ids have and does that mean there is no current purpose of shop ids?

yes there is.
Some shop ID's allow u to still get items that aren't currently in game. I believe an example of this is the Daimyo shop as you can get it even if it is not his birthday.

Really it's just loading shops [and those in that area] that aren't there and sometimes still open rare shops that they don't close.
Not really anything risky, except if AE decides to track purchases or if the shop is a trap due to being rigged/opened by a lot of people.

Yeah, most shops are patched though, but there are people who post working IDs here from time to time.
