They'll need to disable their ad blockers to see your site's content
They need to be able to see your site's content to know whether it is any good.
They won't link to it, promote it on social media, or tell their friends otherwise.
And if they are at work they may not be able to turn off the adblocker anyway.
Even if they don't immediately hit the back button and try the next SERP (the most likely outcome) and go to the trouble of disabling the adblocker (pretty unlikely) the chances of them clicking on any of your ads are as close to "none whatsoever" as makes no difference.
But if it makes you feel better, go for it.
