From what I know, since you have the disclaimer, which clearly states, "IN NO EVENT SHALL SAJHA.COM BE LIABLE TO ANY USER OR ANY THIRD PARTY FOR ANY DAMAGES WHATSOEVER (INCLUDING, WITHOUT LIMITATION, DIRECT, INDIRECT, INCIDENTIAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY OR LOST PROFITS) RESULTING FROM THE USE OR INABILITY TO USE THE WEB SITE OR THE MATERIAL, OR ANY LOSS INCURRED AT AN ADVERTISED or PARTNER or SPONSOR SITE, WHETHER BASED ON WARRANTY, CONTRACT, TORT, OR ANY OTHER LEGAL THEORY, AND WHETHER OR NOT SAJHA.COM IS ADVISED OF THE POSSIBILITY OF SUCH DAMAGES," you should be fine. However, if I were you, I would remove those names(or threads), look into legality issue, and, if wrongly threatened, since u have the written evidence (email), I would look into legality issue to counter-attack.

I expect the the legal experts to come forward and help sajha.

Sincerely,
Megalomaniac.
