Not totaly true. They all will puff some after a hard discharge but are not necessarily bad. I have some that I have been using for years that do this. Follow the rules, use precaution and you will be ok. Good reading here for all

Should I stop using the battery? The batteries have never been damaged.
If they are puffed at all then yes they are damaged and yes that battery is history totally unsafe to use and easily can end up looking like this one. This not just some picture off the net, I took this picture, it happens.
