Heroine's reputation destroyed via internet

Hi to all,

some time ago I read a summary while browsing Goodreads. Unfortunately I forgot to place a bookmark and now it's driving me crazy, because I can't recall title or author.

Here is what I remember (please be aware, that all details are very vague):

She had to deal with the repercussions of this for years, had even quit her studies, as the internet never forgets. I think she received help from a NEIGHBOUR / HERO who might be suffering from some kind of AUTISM / ASPERGERS and then begins to fight back. I don't exactly know if there is a love story as well.

Is someone out there who remembers this plot?
