Yes you can sue, but winning is another thing altogether. First can you prove who wrote the statement? Second, I assume you can prove it is false. Third, can you prove the statement was published? I believe you can based on what you've said. Fourth, can you prove who read the statements? And if you can then how has your character actually been damaged? Do you have other things online that are worse? In other words how will you prove your good name and character have been altered and damaged? These are interesting cases but proving them can be very difficult.
