No, I don’t have heard of such a website. (Although the comment made by Shady_Shiroe comes funnily close to it.) But that is probably because all ad supported sites I visit have more than enough users without adblock to support themselves.
From a pure, real and practical standpoint you are right. For you and me and most users here it won’t do any harm to use adblock. But that only works because there are so many people who don’t. If everyone were to use adblock now, then the websites would start to either find ways to circumvent the adblock or they would not be available anymore, either because they went down or got paywalled. I’m fine with paying for some websites. But there are too many things I think are useful on the internet to be able to pay for each and every thing I see individually or via subscription.
What I want to say is that I don’t think it would be good if a big portion of users would start to use adblock so I don’t think it could be right for any individual person to do so, even if you can’t tell how many more adblock users it would take to make a negative impact.
Not just frequent jokes, but those annoying ever-repeating jokes. Like as if 80% of users were the same person. Before opening any post on Reddit, there is a good chance to be able to correctly predict the exact content of a significant portion of the comments. I get that it can be funny to an individual to come across stuff like “I also choose this guys wife” or “And my axe” more than once. But for people like me, who did not just start using the website, it is really annoying to come across the same jokes literally hundreds of times.
This goes hand in hand with the general idea of a “Reddit hivemind”. Depending on the subs you visit, you can see that Reddits userbase is actually really diverse. There are people from every demographic with all kinds of different life experiences. But in a lot of subs, anytime a woman is mentioned there is a flood of people acting like as if there are no women on the internet and as if no person using Reddit could have a girlfriend. Again, I get that it can be funny once or twice. But when the idea that every user must be a typical “Redditor” gets repeated all the time it’s just annoying. Needless to say that I don’t look forward to being called a “Lemming” on this site.
Also, repeating comments on the same post. Obviously you don’t have to read all the comments if there are already hundreds of them. But if there are too many comments saying the exact same thing it just gets harder to read them all. So it would be nice if people would look whether the point they want to make maybe has been made already. They can increase that comment’s visibility by upvoting. No need to make other people read the same content multiple times and by that make it harder to read different comments.
