Hello Codeforces community,

I don't know why people have so much craze for contribution that they resort to cheap techniques like creating fake accounts and upvoting themselves. Check

One thing how this could be solved is by increasing the time taken to register the account. CF can add fields like "Organization" and other things mandatory and increase the size of the form. I am not into system design, so not sure if I am speaking wrong.

Second the captcha checking system is not functioning full correct. If captcha needs "1042 revenge", then "0000 revenge" also gets accepted. The captcha fails to match the digits (0 - 9). I tried and successfully generated accounts by wrong captcha.

Finally, I have seen useful comments getting downvotes for no reason. Check. Unnecessary downvotes of figures like -111.
It would be better if some trustable users can be added as "Blog Moderators" who could examine and maintain the decorum. :)

Cheers!
