Watch what you write, bloggers! Britney Spears' dad Jamie is taking the #FreeBritney accusations seriously and he's even filed suit against one web site that allegedly defamed him as conservator of Britney's estate, claiming Brit is being controlled against her will.

The suit claims Absolute Britney web site owner Anthony Elia made false and malicious claims that Jamie and his conservatorship controlled Britney's Instagram account to make her seem less stable and more in need of psychiatric help than she actually is, according to Fox News.

"It is time for the conspiracy theories about Britney Spears' well-being and the mob #FreeBritney movement to stop," the lawsuit says in its opening line.

Elia's blog and social media accounts launched the #FreeBritney campaign with numerous conspiracy theories about Brit being held against her will and about her Instagram account being controlled by the conservatorship (aka, Jamie). The suit claims Elia "has made it his mission to spread false and malicious lies on the internet about Britney, her conservatorship and her team, including that those around Britney are harming her and not acting in her best interests."

Beyond these legal issues, Jamie, as conservator, has reportedly received death threats. Sources say followers of the #FreeBritney movement have taken so seriously the conspiracy theories that Brit is being held against her will that they've threatened Jamie's life. Law enforcement has gotten involved.

Meanwhile, the conservatorship was granted an extension on the restraining order against Brit's former manager/friend Sam Lutfi for another five years.

Can you imagine how much they're spending on lawyers!
