Couple of days ago I opened CF on my mobile and it turned out to be having hell lot of ads and pop-ups . I thought that was something with my browser and I tried to access CF using another tablet device and it turns out to have the same annoying ads which doesn't even let me stay in CF page then I thought again this might be about the browser (UC Browser) so I used many different other browser but the same ads and pop-up windows :(
And now I'm using my fresh-installed OS and there are the ads again but not as much as it while browsing CF on my non-desktop devices .
PLEASE STOP THIS ANNOYING POP-UPS .
As a hourly visitor of codeforces I dont find any popup ads at all...
Never happened to me. I don't think codeforces is supposed to have any ads at all.
Looks like these ads are placed by a network provider. Maybe you should contact your ISP to stop the ads.
If CF were to use https then they cannot place ads, correct?
Yes, actually ISP hijacking is the most powerful reason for some websites to enable https.
Do these ads say that a girl nearby wants to date you? It may not be CF.
