I’m not familiar with that board (or any others, besides BOP), but as a general rule, boards that have sponsors (sources) pay to be there are protected, no matter what they do. For the most part, they’re hit or Miss and some are selective scammers. Uncensored (for the most part) boards like Meso are good for holding sources accountable, or at least used to be.
At the end of the day, the only way you’re going to know of a source is trash is by sending your stuff off to be tested, which isn’t cheap. This is mostly why people believe the bullshit of Naps and Pharmacom as they call themselves the most trusted or most tested.
