If it is really working like that, then why you share it here while you can make a lot of profit from it? Once you shared it means that there is big chance for the owner to notice about it and may fix it so you wont be able to make more profit with the trick.
IMO there might be three reasons for the post:
1. OP was lucky and won some money on the site and he/she genuinely thinks that their strategy works and now sharing the strategy with others out of goodwill and charity. It is likely because there is no ref link in their post.
2. OP is trying attract more depositors to the site either being the owner or expecting a reward from the owner.
3. There is indeed a bug in the system (highly unlikely). In this case I suggest the OP to report the bug to the owner and get rewarded instead of sharing with others how to rob the site.
