He's ubiquitous on Youtube. He believes that because he's been a store owner for many years, he's got an edge on which scratchers to buy and when by talking with various customers.
I have a filter that I've developed over the years to distinguish between scammers and one's who may have potential. Thee filters don't always work, but I like it. Whenever you see a person or company selling a product/s over the net, and they plant themselves everywhere, to me it means that they are desperate to sell their product not because it works so well, but because of the profits made from selling it. The desperation reeks. Also sending people endless emails is another flag.
One of the best pair systems I bought was from one reference I saw from searching on the net. The only way to find it was by knowing exactly where to go. You couldn't find it by just typing in the words pick-3 lotteries/ strategies...etc...However, early on, they did have an aggressive ad campaign, but it was short lived. That shows me that they wanted the word to get out, but didn't become annoying by pushing their sales pitches down everyone's throats.
I've seen this Ace Lee guy on many videos and read some info on the net, and I personally don't like him and his sales pitch. Something about him is just not appealing to me, and he sounds devious.
Also, I found out a few months ago that Ace and some other p-3 guru had joined together in an ad campaign that was a little scrupulous. How?, I don't remember the details, but I know it smelled funny.
