Hey MEllsworth,
Whenever I go after links/decide to keep or disavow, I go off of the content of the site more-so than the DA exclusively. High DA is great and all, but I'd rather get a low/medium DA website on a page that has decent stats and the content is about my topic (a bonus if the whole site is on my topic). I could go make a wordpress.com blog in 10 minutes and get a DA 98 link, but that really isn't going to help me in itself.
Regarding your 2 examples, I would attempt to get my link removed and disavow those domains. They don't seem to be about a certain topic but rather anything and everything, plus they have some indications that they are spammy via OSE.
Best of luck - Ryan
