Link on landing page is redirecting to Gambling website

Hello,

I notice that [you link to `pinkmoustache.net` on pjsip.org](https://github.com/pjsip/pjsip-org/blob/c6adc6d9500eb8f9039295b2a2b57a11b342d621/index.htm#L91).
`pinkmoustache.net` is redirecting to `igra1.com`, which is a slot gambling casino website.

Just wanted to make you aware.
