How to find something on somebody's tumblr from ages ago?

[Morecrumble]

I asked somebody a question on tumblr a few weeks ago, and I forgot about it, so didn't check for the answer. I've just remembered about it and I want to know what their answer was, but I cba scrolling through their tumblr to find it, as it would take ages. Is there another way to find.

Also, they do not have an archive so I can't use that.

I don't think so. You could try asking again.
