Typo-squatting most certainly yields tech support pop ups, however, they are very geo-location specific.
If you are coming from an ISP that is outside of the US, you typically will not get the tech support popups.
If you are on a VPN vs. a regular "ISP" connection, you also will receive different targeted ads. Lastly, if you visit multiple sites throughout the day, you will get captcha codes for a lot of the advertisement sites.
The list I have, from another scammer.info member, is as follows:

What I do is go to http://www.openmultipleurl.com in Incognito Mode and paste in the above list. I turn off popup blocking (or allow the domain) and let all of the sites load at once. This has revealed multiple fake tech support popups.
