TvTropes started having a thing that bugs you about having an adblocker.
So I decided to disable adblock for it.
It started lagging to death and crashing because of the ads, as it did before I got adblock.
I reenabled adblock.
Advertisers have, to some extent, brought this upon themselves as well.
Not to mention websites with autoplaying video/audio ads, or pop-ups, or whatever.
