Reading posts such as this and this tells me that there is a significant issue we should address.

Should there be a minimum number of contests for a user to be able to comment, upvote/downvote and post blogs (different number for each, maybe)?

This way, people can't simply make new accounts and upvote/downvote. It would mean upvotes/downvotes are more genuine (less people upvoting reds blindly). It would mean that people are less likely to make many accounts to downvote out of hate.

StackOverflow, for example, doesn't allow users to upvote or downvote unless they have a certain amount of positive contribution. I'm not saying we should do this, but I'm just showing how it can work in practice.

Finally, I know this isn't a new idea and I'm not saying it is perfect. That's why I created a blog so hopefully we can have meaningful discussion about this in the comments, to keep our community healthy.

What are your thoughts?

Thank you!

Hello everyone!

My friend and I were discussing range update and range query of maximum in two dimensions and I am not sure how to implement such a data structure. It appears to be much more difficult than range query/update in one dimensions as it is hard to propagate a tree.

Can anyone provide any insight on this?

Thanks in advance
