Can you say my old account email, becose i want to deactivate it. My old account nickname is @karolis05 and i want to change it on my main account. But i don’t remember my email.
This is a forum for developer questions, not account support. You can read this to figure out how to deactivate your account. https://support.twitter.com/articles/15358
Also, a heads-up, I’m doubting support will in any way give out your email address. If an imposer pretended to be you and asked for your email address, would you be happy they gave it out? They’ll always take extra measures to make sure no information is reached out the account itself.
