Should I disallow links from m.biz?

[EcommerceSite]

Starting in mid February we started receiving links from m.biz, we now have about 14k of them. Some of the example sub-domains are-

http://supply.m.biz/Arabic-Coffee.html

http://wholesale.m.biz/-Agitator-Tank-for-Sale.html

http://supply.m.biz/-For-Sausages.html

http://www.cm.marble.m.biz/Conveyors.html

Should I disallow all of these? It is so many that it would remove half our links. Or is this a legitimate company?

We have seen these domains in audits that we have done as well. However we are also finding hundreds of spin offs of this - examples seekstone.cn and chinastonecompany.com. Like you we have been disavowing them but it would be great if somehow Google could flag up that they are aware of these domains and we don't need to worry about them.

It's not negative SEO.  These links have been turning up in every audit we are doing.

Someone asked John Mueller about links from this site in a recent hangout and he said that Google probably can figure out to ignore these links, but it's not a bad idea to disavow just to be safe so that's what we do.

I was thinking the same thing, but I can't figure out why they are even there. My first thought was someone attempting to negative seo us.

It definitely looks pretty spammy to me. I would probably disavow the domain but it is definitely possible that it could affect your rankings if it has that many links with a ~50 domain authority.

It may be helping you now but I could see it coming back to bite you later.
