Most coins with team members/developers that use their real names and have been around for years you can trust.
Using real names can be faked, "Proof of Developer" was used with many fake ids in order to give the illusion of trust. Basically you can't trust anyone but if they've been around for a while and people aren't complaining about them then they are probably trustworthy. I've had one issue where I paid for some work and the guy was complaining he suffered from massive migraines and then updated Skype that he was in the hospital and then never heard from him again, the work he did for me was a bit shoddy but he kinda delivered and the source was clean. It was a clone of communitycoin and I learnt a fair bit using that source, it was getting him to add in coin control in which I paid 0.5 BTC and then he disappeared so if anything I only overpaid a bit but other than that I haven't had any real issues with people I've met.
I also don't trust newbies and wouldn't download anything from anyone unless getting to know them first, also they could have bought their account. Not sharing personal information freely doesn't make a person untrustworthy, if they've been around for ages then there are probably lots of people that know who they are but just don't share their private information out of respect.

Earning takes time, so asking others for recommendations is probably a bad starting point. Maybe figure out what's most important to you in a coin and then work out which coins have best implemented those features and have the most trust worthy community and devs.
This is good advice.
