Firstly something which no-one has said yet, but thank you to the OP for starting this discussion in the correct forum instead of adding to the threadshitting in Vinces posts that is allowed to go unabated. This is where all this discussion should have taken place from the start, assuming there was any need for discussion (which there isn't).
I think that the threadshitting is the single worst thing about this forum. I've spoken to Dane about it and made reports in threads where it happens. I can't see where anyone has the right to go in to someones simple retail thread and tear the guy to bits for no reason other than you either don't want to buy his product or you believe he owes you something for free if other people want to buy his product.
By all means start another thread about it.
Send a message to the Admin or mods about it if you feel that strongly that he should not be allowed to advertise.
But have some simple bloody manners. :unsure:
As for whether he is doing the right or wrong thing there is no doubt at all that he is acting within the rules, therefore he should be protected from the attacks of a few people by the moderators and admin. That is what you are moderators for people.
Some of the uneducated attacks here from people even suggest that you should get a fee can of goo if you sign up to one of his courses. The person hasn't had the decency to even read the thread in question and understand the courses that are being offered, they just assume that it's a course for newbies to learn how to brew basic beer.
I have no opinion either way, but agree with all the posts that say if you don't care for it, don't click it.
I support everything Bum has said in the original thread and here (aside from the attacks on truman) towards respecting the guy. I would have said this in the thread in retail, but it is not the place for such comments.
I really believe in these instances the moderation team here has failed.
edit for spelling
