I started their but it felt like a dodgy way (as it could be seen to be illegal). We then just went aloffical and went through Google search API’s with LinkedIn as the target. Worked a treat and was cheaper than recruiter!!!

So when pay the highest scraper, it’s ok! Same data, different manner.

Doesn't sound like your operation was particularly questionable, but I can imagine there must be some of those 3,000 extensions where the data flow isn't just "DOM -> End User" but more of a "Dom -> Cloud Server -> ??? -> Profit!" with perhaps a little detour where the end user gets some value too as a hook to justify the extension's existence.
