Ig got this via my contact form:

Hi, I’m ___ and I’m a copywriter for ___, a financial spread betting company. I regularly visit quantlabs.net and really enjoy your content. Currently I’m working on some similar pieces that would suit your site. Would you be interested in some free articles? Thanks,

I am doing just fine with my own  content but thanks. I am sure if you advertise your company but ‘betting’ is a wrong word unless you a betting a newbie with no understanding of risk.
