She's had 109 boyfriends but thinks they were all the problem.

jewess banker: What do you mean I jewed you out of your £200? How dare you accuse me of not paying you your £100. I would never cheat you out of your £25. Wait, you must be mistaken, I don't owe you any money but you should pay me that £300 you owe me.

It's normal. Twitter has a character limit on tweets. Used to be so they would fit in a text message for historical reasons you can look up (it actually used to be an innovative platform) then they made it longer, but there's still a limit which is good for preventing wall of text type content. For longer posts people will reply to themselves. Or sometimes instead of editing a tweet people will reply to themself to add additional thoughts or context.

it happens often enough

I hope your jewdar game is top notch. They get rhinoplasty and change their last names. They blend in pretty well.
