Scammers are sadly a common problem on eBay.
Recently there has been a new wave of more clever scammers.

A bold statement i know, however, true never the less.
Im sure your wondering, "what makes them so clever?"

Well, it seems that these scammers are buying into high feedback accounts in the hope to gain trust of the buyer, ultimately resulting in loss of payment.
These accounts are being sold for large sums of money, accounts with a heatlhy number of positive feedback, which are then being used to scam.

There was once a time where a user with high positive feedback rating, was one that could be easily trusted, but with the age of bulk selling, power selling and massive foriegn importers, building up a high feedback is easy thus resulting in the sale of thier account [knowing full well building up another account would not be troublesome for them]

You're probably wondering now, "this is a guide, so where is the guidance?"

To spot this new age scam, it is wise to check the users recent feedback, noting down thier feedback rating would not suffice, instead view their last 5-10 feedback left, try to spot a pattern with the dates recieved.
Many of the high volume sellers will have recieved thier feedback one soon after the other. Therefore if you notice a gap from their last positive feedback to the date of the listing your interested in [in some cases upto 3months without feedback, then suddenly, a top of the range mobile phone listed at an unbeatable price] then that user had most likely bought into this account thus a scam.

Now im sure this guide would not appeal to those honest ebay users that simply dont sell every day of every month, as im pretty much branding them as scammers, but please use your initiative.
If the item for sale is too good to be true, and they have high feedback, CHECK IT, see if the is a gap between, what looks like alot of feedback, and the time of listing. If the gap is large, then beware.

Good luck and happy eBay'ing
