Reading 1000 posts can be done.
Especially if you really like the person and most of the posts..

Methodology is everything in reading everything, for example:

Choose one of these ways to read profile posts:

█10 posts x 100 looks

█20 posts x 50 looks

█50 posts x 20 looks

Keeping window open helps or bookmarked where you won't forget.

These options allow you to bite-sized time frames, say 10mins each time (in 'bite-sized' smaller portions to achieve all the posts / smaller time)

ℹ️ I just did 248 posts in one go because the profile had mostly one line of text for each message.

❓ IS IT POSSIBLE WITH LONGER BLOG POSTS?

✔️ YES - do same with long blog posts from someone you really like 'reading' in this longer post context can mean; look at title, maybe click to check out more BUT skip if you find out it's not for you. 10 posts can be like 5 instantly closed or not even opened is title is clear.
