If someone says "i got this info from a sasaeng", does that necessarily make what they say true?

It makes what they say instantly false. lol

Maybe, but not really.

sasaengs are very weird to me but i would go 50/50 with it if someone told me that

Depends on if they are actually telling the truth about if they got from a sasaeng. Then even if they are telling the truth, there is a possibility that they were tricked about whether the person was actually a sasaeng. People have been scammed like that by a fake for fake information.

No, saesangs actually lie a lot

Real sasaeng won't easily leaked any 'tea' unless their faves disappoint them

Probably not, I’d want to get my news from more authoritative sources.

I have saesang info about all your faves. Trust me

I take only 10 akorns for each idol

no matter where the info came from, be it sasaeng, a friend, a fan, a random tweet, etc... better ask for proof or receipts.

Chuu is a feared gang leader, I got this info from a sasaeng

It's all on the 'trust me bro' basis. A rumor is still a rumor, no matter where it comes from. I would say ESPECIALLY on english-speaking website, it's 99% bullshit and 1% lucky guess.
