Probably you have malware or virus on your PC that damages the software and eventually the hardware parts of the PC. I do not think that CPU were being use to mine and there is no relevance between mining and gambling site. If it does and the developer does not told the user about this then you can make a complain in their site.

This is the first time I have seen a discussion where gambling site has been integrated to mining. Probably there would be but chances are low. There should be more reason behind the program getting crashed or why the PC is hot after running the autobet program.
