What would be accurate sources of trust for a trust score system?


First of all, sorry if the title came out a little vague.

So I am working on a group that involves a lot of Roleplaying, and I am working on a trust score system to check players that are most and least likely to be Alts.

I need to know some accurate sources like Account Age which I can use.

Thanks in advance.

You need to change your title, it is worded very oddly.

I think an account age of 3 weeks should be fine, a hacker would get bored of waiting by then.
