Can trust these tokens just because PS listed them on its farm ?
No! Anyone can list their token on Pancakeswap and Pancakeswap does not regulate token listing. For example, the recent mainstream Squid Game token scam are listed there and you know how it end up. I suggest you shouldn't lure to play around within it just because it has a tremendously high APR, especially if you didn't know what are you doing. It's literally anyone can simply list a token there, you should beware of it.
