I can't speak for kerabatsos, but when I see something like "How my paid community made $5K in it's first week", I tend to automatically add "... and YOU CAN TOO, with my special patented secret methods!"

Writing like that is bait, because it will generate money from marks without even verifying whether the claim is true. If I take the bait, then I'm a sucker, and I'd rather keep my money and not be a sucker. To turn phrases in that way is sensationalism, and while I'm sure it works for you, I believe it trades short term cash for long term trust. When the next sucker finds that he can't reproduce your results, there's a good chance he'll feel shafted.
