I repeat, that site is worthless.
I completely disagree.
Yes it's the work of one person (read his 'My Story' page on it).
It may well have many flaws, from a scientific / methods perspective.
So what? Does that make it worthless?
I first came across lostallhope many years ago, when at the time I was in a very dark place and could find little else that discussed suicide. It predates SaSu by some time.
His 'Links' page is a decent attempt at being comprehensive (maybe some of us should contact him to recommend he add a link to SaSu). Overall it's trying to provide an open, helpful resource about suicide. I think it is that.
I think we need more sites like this to bring attention to the fact that this topic deserves serious attention from mainstream society, not less.
You are free to disagree.
Give it a break, perhaps?
Or why not build your own website to show us all how it should be done.
