However from his first post on his distaste for being spammed by wholesalers we went back and forth on that thread  into the tulles and we both worked in the same area at basically the same time ( which I suspect was before 80% of BP members were born LOL) and he knew the players of the day  so to me it verified his past experiences.

Its definetaly a gamble unless you have personal info on the owners, deceased, no heirs, in prison, etc. 

However, if someone wants to take legal action against someone lives outside the US for a spam message, the costs and procedures would be different, right?

For example - the seller can use it for their due diligence fee, pay off a credit card, pay off a medical bill, gamble, buy a bathtub full of gold, etc. the moment they receive it (normally the day after the offer is accepted).

While I currently utilize Facebook groups, the platform often involves spam.

I tried to do it in private messaging but It was shut down as spam.

Either way is a gamble but if they are a legitimate business you may have a chance at 25-50 cents on the dollar or more and that's a better return than zero.

I gambled what I could afford to lose, just I don't like losing.

Gambling on yourself in REI by liquidating your retirement without first having any experience, is very bad advice, imo. 

So I don't gamble on it.
