I want to curate a special topic on my Tumblr, so I'm trying to reblog everything related. After months and hundreds of posts, it's hard to know if I reblogged something already.
Because I don't want to duplicate a reblog, I check if my Tumblr is listed in the "Notes" list of a post. Unfortunately, this list can become very long and I'd have to click "Show more notes" and on each page search for my name.
Is there an easier way to check if I already reblogged a post?
If not as a function in Tumblr itself, maybe with a 3rd-party service or with a custom API call (so I could built a service myself, if it is easy)?
(It's not my main blog but a sub-blog, if it matters.)
