In my google webmaster tools a site has been building 10-25 crappy links a day to my site for past 2 months. In total there are 1300 links and growing. Ive been monitoring the situation but what is really strange, when I try to visit the links(different hours on different days past month), it's always down because of bandwidth limit. Just wondering if this some sort of tactic or if anyone experience this. Since it constantly down, how is this person even building links and how is google picking up the link? These links are coming from different subdomain of same domain. Im not getting any errors in G Webmaster tools, so I'm not sure if I should start disavowing the links or just leave it & build strong links. If anyone can suggest what I should do or point me to right information, that be great. Peace out.
