I find posts and comments from Mastodon to be almost unreadable because they are loaded with hashtags in-line with the content.

Would it be possible to strip those out when viewed through Piefed?

Most of mastodon users writes the hashtags in the body text, probably due to their character's limitation.

So, on piefed, if we want to keep their message and make them readable, i think we would have to :

• put detected hashtags in the hashtag field (we should do the same for peertube's video).
• then remove the #, and separate words with camelCase.

And for the coding part, i can't answer it. :)

Ideally as a settings toggle

If this were to be implemented, I’d like it to be something users can toggle in their settings.

Changes to the original post should be avoided as much as possible.

Maybe, wrap the tags in a “tags” block that mimics spoiler markup?

That way, they aren’t deleted but are hidden. A setting could manage whether they are automatically collapsed.
