For opsec purposes, some members like to use apps like telegram or other private communication channels.

However, the downside is that the seller can delete your messages, therefore removing all proof of your transaction.
Also sinister.ly only ban scammers if you make the transaction on the site as proof on other sites is not verifiable.

I did a deal with a platninum member with rep, who sells services here but got scammed for $150.
You can read my scam report about it.

So if you use private communcation channels, what you gain in privacy you also increase your risk in losing your money as it is very easy to delete the proof.

My tip is dont give too much trust based on a forum members rep.
