This girl is stalking me on Twitter, what should I do?

[Daisy]

She keeps constantly messaging me, tweeting me, retweeting my tweets and all of that. Every time I don't reply or I'm not online, she messages me every 5 minutes saying am I there or that i'm ignoring her. It's really starting to annoy me. Every time I try and message my friends on twitter or write a status, she always intrudes and comments on them, even if they aren't related to her. I can't block her though because i know her in real life and she'll be really offended and I don't want to fall out with her. What should I do?

DDoS her, if you take her offline she can't do anything
F*ck the police

Just delete her

or block her

Talk to her and say if she does not stop you will have to block her. Or take a step back from social media all together. It is quite liberating doing so.
