I am PRO FOLLOW for Customers
Customers DO use the follow function and I definitely do not want to remove that option for them. Them being able to find me easily (if they want to) is important especially as sometimes I tweak my store names.
Stopping other designers from following is fine, I have no problem re that as it has no benefit that I can see.
I don't really pay much attention to the follow, but I just wanted to add that designers are buyers too. I like to support fellow designers when I can and when they have things that I don't make myself so I wouldn't want to stop someone from following me just because they are a designer.
