I'm surprised you feel this way. Since you post there, you must think there's some value to be found on PDF. Most news and information is posted there first and some never makes it here. In my view, there is a comparable number of good posters on both forums; while PDF has a lot of open trolling, SDF has other issues.
In this case, the two comments are from 星海军事 and another one by rcrmj, where he was relaying info from gongke101.
Agreed and there are indeed a few - but very few - IMO reliable posters. Especially on the one you mention you are correct.
Sorry.
