They will openly say this and still the US does nothing to stop it

Hmm I think it’s fine if someone is a social butterfly, they don’t have bad intentions etc. I am talking about someone who seems like you can trust them but actually they have other loyalties, I live in a place where people get arrested for supporting democracy for example

I am not really understanding this, anyway I am looking for a word for someone who will be friends with pro-govt and pro-democracy people and you can’t trust a person like this or you will get arrested

I live in Asia, if you tell the wrong person you are a democracy supporter you can get arrested or on a watch list

sorry what do you mean? english is not my first language

I’ve had friends that were friends with ex-cons, etc.

you do you but I would definitely want to know if my friends were close with people who’d been in prison. If I worked in a field where they do background checks i would absolutely need to know if my friends were friends with those in prison. There’s a difference between dictating who people are friends with and knowing who people you give information to are close with.

If you’re friends with someone, wouldn’t you want to know if they’re also friends with someone problematic?

disingenuous

disingenuous could definitely be it; they’re not straightforward about their intentions.

Opportunist is definitely closer to what i’m thinking than sycophant.

They keep their connections hidden; it is the other groups who when asked state that they are friendly with this person.
