Not sure, what is the case of it. But will merge it

Sorry, meant to add a justification!

I noticed that the pinned tweet always gets included in the results, regardless of date. So for example, if you try producing results for Twitter username 'medialens' or 'ggreenwald' without any specific option checked, the very last item in the results (dated 2018) will be the pinned tweet. All the other items are dated 2021. To me, this doesn't make much sense in RSS output, which should just be the latest items. Of course, many RSS readers will pull in this item once and just ignore it as a repeat item when checking the feed in the future, but it still feels wrong to have it always included in the feed, especially when there's a big date discrepancy with the other items.

A similar issue to the above: Let's say there's a Twitter account that primarily retweets but also has some original tweets. If you enable 'without retweets' in RSS Bridge, you will not get any original tweets if all the recent tweets have only been retweets. If there's a pinned tweet, however, that will show up as the only original tweet, even if there are more recent original tweets. I noticed this when experimenting with our Twitter account 'fivefilters'.

There is however the issue that if 'without pinned tweet' is enabled, and a new tweet is immediately marked as pinned by its author, it might never find its way into the RSS-Bridge RSS feed.
