My mum stalks me on twitter and everything. How can I get her out?

[560]

So one time I tweeted "flooded my bathroom again...oops" and she replied "something to be proud of I suppose" like why the hell does she has twitter , she's like 40 and doesn't need it! And then I blocked her, and now she is stalking me like going on my ipad or something and reading my dm's to people. One was to my best friend saying that some guy who was decent liking was fit who follows her, only becaus she sed I have loads of fit followers or famous later on in the day, so I messaged her to make her feel better than this guy was fit! And my mum saw it! She's soooo judgemental !!! And I asked this girl to ask him to follow me cos he is like kinda half famous. And I tweeted him saying "follow be please im your biggest fan #loveyou" and now I bet my mum thinks I'm some freak who is obsessed wth fit people!!!! How can I get her not to stalk me?
