I wanted to paste a quote from the Tutor Guide, as already mentioned- "In order to be appointed as tutor, you must have obtained 40 "Thank you!'s" by different players in the last 90 days." Source- Tutor Guide
I wanted to share with you some additional information from my research on limitations if we can get more than one thank you for an answer to become a Tutor, I hope it's helpful-
According to the rule 4.1B from tutor guide, you need receive 40 "Thank you" from diferent players, the rule doesn’t specify that they need to be different answers.
So, yes, you can get more than one "thank you" for an answer.
