I thought Twitter already had limits, tbh. It only ever has so many curated tweets for me, few of which are from accounts that I actually follow (even fewer from radical tweeters). After a few ‘pages’ it just says, ‘no’, and refuses to load any more. It’s always done this. If I click on the profiles of people I do follow, many tweet daily and often. Twitter just refuses to include them in my timeline. It’s one of the reasons I rarely use it. No idea what it would be like recently.
