AdBlock is quite wrong to sites who highly rely on them for their income. Unfortunate alot of the adds are way to intrusive and in the way of the sites content. This is a reason why I use it to keep an enjoyable browsing experience.
But, you can blacklist sites in it's settings so AdBlock won't filter those ads so you can support them. I do that with some Twitch streamers who I want to support and sites with non-intrusive adds.
