Make anti-DDoS weaker
By brezhart, history, 20 months ago, In English

Updating submission 4 times in a row resulting short temporary ban and it's so annoying. Can you make anti-ddos more weaker? Maybe do it more tolerant toward "trusted" users, where trusted can be defined as you like: big rating, old account, big contrib, idk. Pls do something...

Exactlyyyyyyyyy. This has become so annoying , every time its checking security, clicking those you are not a robot like its not codeforces but pornforces. wayyyyy tooo much confirm form resubmission man. Simplicity is the key guys. BTW is it the reason why codeforces visualizer is not working properly these days, half the time it goes like couldn't find user.

I agree, the anti-DDoS is becoming not just a problem for human users but for legitimate bots trying to access data as well. I've noticed that both the USACO TLE bot as well as a lockout bot I'm hosting give CF API error ever since the change happened, so I think it's related to that. MikeMirzayanov could you please fix this or suggest a workaround?

Yeah, it's super annoying. If you submit a solution, it checks the security. If you open a problem, it checks the security. Sometimes even with upvoting it checks the security. It's not just time consuming, but it needs a ton of internet. Codeforces was the least internet consuming website, now it took 500 mega bytes from my internet bundle in one day! It used to take like 50 at most!!

      Believe it or not, there are still countries where internet access is not as universal as in others. And it's not just the volume of data consumption, it's also the speed of internet connections that makes it worse.

true this anti DDOS system makes the process slow as well as annoying for most of the users like in the last contest the server issue came N no. of times and after those errors the loading time that anti DDOS takes just annoyed me and I left the contest , I guess the moderators and Officials needs to come up with a better solution or Atleast some crucial changes are needed , as in a running contest we need a good environment and smooth processing of the site
