There was a new ban enacted in Jan/Feb of this year that caused all makers and websites to reformulate in the US. Selling 2-4 year old blends with old formulations would be illegal, and dangerous to your customers and yourself, would it not? Sounds like something you would want to take to a DNM and not a clearnet website.
You think because the site is private and hasn't accepted new members here in a while that it still isn't watched by LE with accounts that are 2 years old or have been here longer? This website doesn't even have an SSL certificate and I see no HTTPS connections being made. It's all cleartext man.... but as long as it's okay with you guys...good luck.
There are 154 members here, you seriously can say without a doubt you know them all personally? You and I know that can't be completely accurate.
