Websites need to generate revenue. If you run a torrent site you are probably well aware that those who visit your site are craftier than your average web user. If people are using ad blockers then you aren't able to generate revenue to pay for hosting and your own time maintaining things. Your option then is to try your best to make the ads on your site even craftier to try and bypass adblockers so you can monetize. Your other option is to let all the ads get blocked, get no revenue, make the website become solely your financial burden.... Or you know. Your users disable the adblockers when on your site and the ads won't have to be so aggressive and your site can monetize.
