Gumtree and eBay scammers!!!!!

There's 2 scammers I've came across because I'm very lucky, it just happened that I was looking to purchase a new car an a new motorbike, to which I came across 2 scams with names of:
"SABRINA"------- [email protected] (Selling Nissan Gt-R35)
"SARAH"--------- [email protected] (Selling Ducati 1198)
They both advertise on both eBay and gumtree (probably more places to, after all there scammers), I've been intouch with eBay and they say they are both members etc, and say that "YOUR" covered with there 'eBay buyers protection', I've read this is bullsh*t, it's something to do with where the money gets actually payed to or something, so please "DO NOT, DO NOT" fall for this!!!!!
When I emailed both these scammers at different times regarding the 2 different scams, I only inquired about the bike and car (bearing in mind two different people, two different things), in queries where the general, ie- any finance owed, been crashes etc, just the normal questions as we all ask, to which both replied very similar emails, only difference was that SABRINA (the silly bit*h, I mean teenage witch) said she'd moved to Spain (Barcelona) an the car was there, (yawn, yawn, ring, ring), alarm bells rung pretty loud, an she'd pay for the car to be delivered all in with the price, if I didn't like it blah, blah, blah, she'd pay for it to be returned at her expense, hmmmmmm!!!!
As for SARAH (sh*t bag) 'SHE' is working in Scotland, but unfortunately for me (awwwww) her bike is else where, so I can't view it, because she's obviously sabrinas long lost sister (to which I know as they have the same type of heart), was going to get the bike sent to my address, (I know, 2 lovely women, wish they were as selfish as you honest lot an just made me travel to theirs, after all I'm saving them money, ahhhh here's me thinking there the problem, maybe I'm not used to kindness)
So going back to me saying they both emailed the same thing, that thing was the run down on how I'm covered through eBay AND PayPal, as to which no monies, or anything where even mentioned, I was under the impression they were both getting sold through gumtree, not eBay, so if you get a similar thing to this about how your covered etc in the first email they send you, I've found it's been a scam, famous saying of 'if it sounds to good to be true, then it DEFINITELY is' please remember this, hate people like this who should be locked up or beating to a pulp by whom they've scammed thanks and sorry for ranting on, kind regards Gary!!
(Ps guys, SABRINA and SARAH, hmmmmm......... Lesson to be learnt, don't trust a sale when a women's involved lol, just joking ladies, please don't be offended, wife will thick lug me don't worry and really sorry for the people who have been told to late about the scams or have found out the hard way, first hand experience, damn 'A' Holes they are, and sorry for the genuine sellers/buyers who are legit from abroad etc, if there are any x)

As an online seller I got scammed a couple of times by buyers that abuse the PayPal system to get free items. I will post them in this topic since the title seems right.

First is the eBay user mini_pro_shop. He bought and item with a total worth of $20 from me. He did not use the possibility to pay extra for a tracking number.
The item was shipped to this address:
JING FAN ZHOU
1546 rue Dézéry
MONTRÉAL QC H1W 2R4
Canada

And payment was made by this e-mail address:
Chang Liu - [email protected]

The item was shipped from Europe to Canada, this may take up to 14 days for an item to arrive. This person took only half a day after the shipment was made to open a PayPal claim.
Immediately he was very rude and demanding a refund because I did not have a tracking number. This is a BS demand because he had the option to have it shipped with a tracking number but chose not to get one.
After multiple times trying to explain that there is no tracking number and that I will arrive but it needs some time he kept sending me rude messages and e-mails. As soon as he has the opportinuty the PayPal/eBay claim got escalated and he got refunded. Even before the estimated time or arrival!
I tried to explain this multiple times but no answers to this. To finish the deal he left me a negative feedback, claiming that I use offensive language towards him and that I discriminate/ am a racist.

This person knew from the moment he made the payment that he would get his money back.

Edit

hello onlineseller and welcome to Scamwarners,

This is speculation on my part. The scammer probably asked for the no tracking option because he probably does not live at the claimed address. The house at that address recently sold and may have been vacant at the time you made the shipment.
Scammers often use legitimate real estate and rental listings in their scams to add credibility.
