Oh of course it is. That’s the correct way to play, simple as that. Any site that tells a user how to play basic strategy is helping to ensure that they lose the least possible and therefore providing a useful service.
But the OPs strategy implies it does more than that – it implies it helps you win, rather than simply lose as little as possible.
Of course I have nothing against basic strategy – and if there was a strategy that really meant you could win (beat the HA), then I’d have nothing against that either 
But the latter doesn’t exist, so what I take issue with is any site that claims it does exist.
I feel that the OPs strategy unrealistically sets the expectation that it is possible to ‘beat the house’ at craps. Furthermore it does this in a way that encourages people to sign up and try real money to test it. Therefore it is misleading and, in my opinion, dishonest.
Actually you’re right here – I just checked WOO and Playtech does have better odds than some other casinos. Their HA is around 0.47% compared to 0.85%.
So yes, it is correct to say that Playtech is the best (or one of the best) places to play craps.
But as you say, that simply means you lose less – not that you can ever expect to win (in the long run).
What I take issue with is the fact that the OP’s site seems to heavily imply that this is a winning strategy. In fact his strategy makes no difference whatsoever – you will win, lose, or draw just as often without the strategy as you will with it, and your overall lose will be just the same with or without it. (As always, in the long run)
Looking at his site again, these are the statements I take issue with:
“Random sequence is not programmed in an internet casino. The software simply delivers winning percentage to the casino. This fact creates the vulnerability exploited by the system”
This is complete nonsense. All (reputable) online casino play is governed by a random number generator. It will generate a random number that is then translated into a game result – in Craps, it will generate a random number that becomes the dice throw.
The software absolutely does not “deliver a winning percentage to the casino” – it simply generates random results. It is the rules of the game that govern the winning percentage.
There is no ‘vulnerability’ at all – the last sentence above is therefore pure falacy. This system will win just the same as flat betting.
“Player survey indicates Playtech software as being most statistically vunerable to this strategy”
Again, pure fantasy. Yes you lose less on Playtech because their rules are better. But it’s not ‘vulnerable’ to anything.
If I devised a craps system that involved standing on one leg, rubbing my stomach and shouting “wibble!” every time I placed a Don’t Pass bet, I would find that I would do better at Playtech than I would at other casinos. This does not indicate that Playtech is vulnerable to my system, or indeed that my system does anything at all.
And finally – the standard question/test of any gambling system. If it really works, why isn’t the OP out using making lots of money rather than offering it free to his affiliate users?
It doesn’t work, it’s snake oil, and the OP hopes to attract gamblers who think they can beat the house using his system. In my book that’s dishonest.
