Hi - sorry but that is rubbish with regards other snipers. I spoke to eBay myself regarding the issue. They were quite clear they had no intention of blocking snipers - in the main because it would drive shoppers elsewhere.
I had a sequence of failed snipes using AS - with the occasional odd one or two being placed. It got to a 90% fail rate - i.e. totally unreliable. IMMEDIATELY I switched to the other sniper (which by the way is completely free) every single one of my (over 100 now) bids was placed successfully. I reiterate: NOT ONE SINGLE FAILED BID PLACEMENT.
So I don't buy it is an across the board problem for all sniping companies. It most definitely is a problem for AS though.
There customer service is woeful and when I did get a reply it was just a scripted response with no answers to the questions posed. They did little to nothing to sort the problem out - and you have to pay for their service when the sniper I use is free and so far 100% proficient.
I would never go back to them now - I mean why would I?
