I dont think this point it totally fair/true:
Are they asking you to trust them? (red flag)
Anyone starting out trying to gain trust but are totally legit, may say these words. Unless the person is begging, thats a different story
True, but if someone is just starting out, they would probably be best served by making a proposal and then leaving it to the more experienced party to decide whether or not to trust them.
Everyone wants to be trustworthy (at least normal people), but on the internet especially, these things take time.
My rule: Everyone lives in Nigeria...until they prove the don't
p.s. No offense meant to honest Nigerians
