Well I’d exchange links with your site, mainly because it looks great and seems informative. Unfortunately I also get a lot of spam emails regarding links and most of are from automated spiders and end up in the bin because they are they are just spam, or porn, or have nothing to do with gambling. I have stopped requesting links because it is too much hassle to check them after etc, but if a decent site requests one from me I’ll have it on within a couple of days depending how busy I am.
The thing is in SEO forums we are told that Google devalues off topic links so maybe your site is a testament to the contrary? In any case well done in the serps!
