Yes this forum is definitely a good place to find out which is a scam and not. If someone offers something to you and you find out nothing about them here in the forum, that's probably just one of the scam attempt. so make sure they are here in the forum and had posted an ANN thread.
You see them everyday with new accounts in the forum offering investments that are too good to be true. Its not just investments actually, some are selling something else like digital products and so on. If they mentione about sending your BTC first, thats something to be alarmed.
Many people may offer you things that may seem to be very attractive .
But you have to be smart enough to judge that deal.
The best way to judge a scammer is see his trust-
If it's negative then do not trust at all.
If it's neutral still do not trust.
If it's positive then you may trade with him but still be alert.
And also don't get into trap of some services,
unless they are from reliable sources like famous campaigns.
After getting this much info I don't think you will have any problem.
