There is a website that I actually noticed a few years ago called RSSING.com that copies (some would say scrapes) RSS feeds from various websites.
FBOFW they have copied many pages from DSLR.
You can go here:
https://www.rssing.com/search.php?q=dslreports.com#gsc.tab=0&gsc.q=dslreports.com&gsc.page=1
This brings up a Search Box.
To narrow down searches, ADD the specific term you are looking for.
For example, to look up DSLR content for Verizon, the terms inside the Search Box would be:
dslreports.com Verizon
Another example, to look up DSLR content for Grandstream (phones) the Search Box should say:
dslreports.com Grandstream
Hope this may be useful....
