100% chance that stackoverflow will be sending nasty notes to the author (who appears to live in the US). 100% chance he'll have to take it down or change the name.

You really can't use the exact name of the people you are cloning. Even something like "stackrobot" would risky. Safest thing is to not use any words from the original product.

Call it SObot, as in Stack Overflow Robot, but without using the name “Stack Overflow”.

They don't need to send notes, they can just take it over under cybersquatting laws. Although, that is for US TLDs not .gg.
