Skip having a Twitter account, i know you are smarter than that.

Step 1. Go on Nitter;
Step 2. Search your Twitter users;
Step 3. Get their Nitter RSS links and paste into your RSS reader (for example 'Feeder' app).

Profit. You'll get all their posts and you don't have to ever touch Twitter shithole site/app.
