I will soon be taking a similar approach, I don't feel comfortable sending traffic to sites that employ such tactics to keep themselves afloat.
Many of these sites have zero regards for the ecosystem - don't feature any sort of Bitcoin advertising and have almost zero relevant content apart from the satoshis they offer. For sites that actually work to develop their sites, it really sucks to lose traffic to these juggernauts. Nobody can afford to offer what they do without employing those sort of tactics.
It's a shame looking at the top 10 on iFaucet. 90% of the faucets listed have anti-bot links.
