I have a site that I know was Domain Authority 35 but now Domain Authority 25 after someone sent a load of spam links to it, how can this be correct and how can I change it? Is it worth doing a disavow and will moz take that into account?

Can any of you guys please help me I have alerts on links coming in and it looks like recently someone did this, it looks maliciously done as it is only our domain mentioned and most are brand new posts? http://testosteroneclinicindenve53950.shotblogs.com/testosterone-clinic-in-denver-fundamentals-explained-6102386 http://claytondmnnp.ampedpages.com/Details-Fiction-and-testosterone-clinic-in-denver-16897309 http://vinylvehiclecarwrap38041.alltdesign.com/a-review-of-vinyl-vehicle-car-wrap-9574042 http://devinxccct.educationalimpactblog.com/1784474/little-known-facts-about-vinyl-vehicle-car-wrap http://keeganbsftf.ka-blogs.com/7488539/how-vinyl-vehicle-car-wrap-can-save-you-time-stress-and-money http://andybxoes.thezenweb.com/vinyl-vehicle-car-wrap-Fundamentals-Explained-17581028 http://kylerhfdzu.blogkoo.com/not-known-details-about-vinyl-vehicle-car-wrap-9029141 http://troyytkyn.timeblog.net/7695911/the-greatest-guide-to-vinyl-vehicle-car-wrap http://waylontyzab.pointblog.net/testosterone-clinic-in-denver-Secrets-16335972 http://testosteroneclinicindenve30516.onesmablog.com/Top-testosterone-clinic-in-denver-Secrets-17252737 http://emiliogkmop.blogofoto.com/7667522/top-guidelines-of-testosterone-clinic-in-denver http://caidenaczxt.blogs-service.com/7514172/testosterone-clinic-in-denver-fundamentals-explained http://daltonpyfms.mybjjblog.com/5-simple-statements-about-testosterone-clinic-in-denver-explained-6517932 Should I try to disavow these and submit to google or will google know our site which has been up for 5 years is not doing this? Should I do any of these https://tehnoblog.org/google-webmaster-tools-my-website-got-bombed-with-backlinks-what-to-do/

We own this site http://www.discountstickerprinting.co.uk/ and just a little concerned as I right clicked open in new tab on the tab content section and it went to a new page For example if you right click on the price tab and click open in new tab you will end up with the url
http://www.discountstickerprinting.co.uk/#tabThree Does this mean that our content is being duplicated onto another page? If so what should I do?

I always thought that the link colour has to be different from text colour? I have come across a site http://www.printandpackaging.co.uk/ and it has made me question this belief, they seem to only have bolded the link which would be very nice if this is  fine.

I am currently building links to our website via estalished blogs ect (2+ years old), As far as I understand even if they are unrelated to what we do (print) as long as the post is about print the link should offer some value is this correct? Other questions I have which I would greatly appreciate advice in are as follows........ (1) Do charity websites or company websites with link pages ( about5-10 other links) or links / logo's on the front page offer value even on unrelated sites? (2) What happens if 80% of the link building I am doing comes from blogs? (3) If I have links that are clearly spam that have been built to our site can they be damaging our potential to rank and how can I remove them as I have tried to contact the relevant parties but fear pressing the button on the google tool may harm our site should I? (4) If I have a page that genuinely has a lot of mentions of a keyword (not so much the money keyword but part such as wanting to rank for pool table but end up with the different versions of keywords having table mentioned 5 - 10% of the time). Thank you for your time.
