I have a .ninja email and get the same a lot to the extend where I explicitly say "it ends in .ninja with no .com or anything".
Usually use [email protected] whenever I make online purchases, and I had a guy from a small shop call me up and ask why I had an email with his company name on. Took some good fifteen minutes to explain him that I was legit and owned the domain. He was still reluctant in the end, but eventually ended the conversation with something along the lines of "it's your problem, not mine, if the parcel won't reach you for using a fake email" :)
GPT-4 costs 30 times more than gpt-3.5-turbo and 60ktimes more if you use the 32k token gpt-4 model. It's by far their most expensive service!
I'm using gpt-3.5-turbo, also for coding, and honestly it does just fine.
