Our 8-digit IDs on /bant/ are randomly generated from small a-z, capital A-Z, +, /, and number 0-9
That is 26 + 26 + 2 + 10 = 64, so the probability of getting an ID is 64^-8

And there are only 6 patterns to get "kot" ID as follows:
kot*****
*kot****
**kot***
***kot**
****kot*
*****kot

Therefore, the probability of getting "kot" ID is
64^-8 x 6 = 2.1 x 10^-14 = 0.0000000000021%

Furthermore, the probability becomes considerably lower that his post is also "kot"
