I like to do this with every single trade I do just in case so that I avoid chargebacks and potential disputes.
This is mainly for sellers as you won't know the buyer.
Once they add you, follow these steps:
Add them back.
Right click their Skype name
Click "View Profile"
There will be a part which says, Skype: ********* (This is what's called a Skype ID)
Copy the Skype ID
Load up google
Search the following, "Their Skype ID"
It will narrow all results down to what contains their exact Skype ID which will potentially be scam reports and all of their linked forum accounts
Check their reddit account isn't banned etc, they may be linked to MPGH so check they aren't banned there too and whatever else comes up
For example,
Someone said they were scammed by a Skype ID of "alex.donald792".
Search "alex.donald792" in google to receive the following,
https://gyazo.com/6b9f2dc515707d2466f269dab6432b2f
You've now found that he is a Reddit user, look through the results and go to his Reddit account.
In this case its "Obama2k15"

Go to his profile to find this,
https://gyazo.com/3b8de0ae59d2372460643638755ac987
Now you have multiple posts about him being a scammer and therefore you should never go first and be cautious, you can also go through the scam reports to make your judgement on if he is a scammer or not or to see if it was marked as him not being a scammer.
This is just a simple way to find people who are previous scammers using the same Skype...
Literally no one knows this somehow
(Posted this on Reddit and it got stickied a while back, turned out no one knew about this method.. Idk if its anywhere in this section but its useful information @Raple @059 @Ahlwong you can modify it and add it to a safe trading thread or whatever, I don't mind.)
Copied and pasted it so it may be scruffy due to the difference between Reddit and MPGH.
Enjoy
