I think the "grey" area is whether the item is a direct competitor... My understanding is as follows (with examples)
Dai's Buugeng can only be bought from him - HoP don't sell S-staffs or anything similar so it's more a point of information that they're talked about here.
Glow poi however are available on here, and Flowtoys are a direct competitor. Discussing their pros/cons is fine as HoP products may/may not come out favourably. However blatantly saying "Check out these new glow poi, they're amazing, but them at
www.randompoimake.com" is different.
I believe (though could be wrong) Hyperlights are possibly to be sold from HoP hence that thread...
Paid-for workshops/classes are tolerated as again they don't directly compete with anything HoP sells...
There was a thread somewhere on HoP earlier about advertising and what was/wasn't accepted - ultimately it comes down to Malcolm/George
