Should I disavow links from eBay?

[cj2600]

Hi guys, I need your help.
I'm running a small site with <widget> repair instructions.
I guess lots of eBay sellers are linking to my site because of these instructions.
Webmaster Tools shows over 35000 links coming from eBay from 10 different countries.
It's over 40% of all incoming links!
Are eBay links considered to be spam links?
Should I disavow eBay links?
Have you done that? Any improvements?


My site has been loosing traffic since January 2012. Gradually went down from about 14000 visits/day to about 2000/visits day.

Thanks!

These are natural links, but what is the anchor text on these links from eBay? If it is a plain URL or something like "here" I would not worry at all.

Keep them. This is exactly what Google wants to see. Don't get much more natural than this.

Thanks for your responses guys.

@ aakk9999
Yeah, it's either "click here" or plain URL of my page.

@ Shai
I guess I'll keep them. These links developed over time.

I just was worried that too many links coming from one domain. But what can I do? They ARE natural.
