I don't think that you should be banned for that , you didn't scammed anyone.
You just wanted to help our members do not buy it and waste their money(well it was only 2-3$)

Loget you are wrong such a trusted member like Sandin0 - doesn't deserve this

EDIT: george i respect your work but seems like your tutorial is too bad and most of us knows about those tips which you wrote, i don't have nothing against you btw .. do not take it very srsly im just telling the truth
