Attempted Instagram account hack

Someone has been trying to get into my Instagram and email accounts...

Just wondered if the person succeeds, is there a way I can find out what name they've changed the Instagram account to? (presuming they will)

This ALWAYS happens with any popular instagram accounts I have. Everytime I switch to a different account and then try to log back in Instagram says they have reset my password due to too many failed log in attempts. This happens like no joke twice a week. And sometimes Instagrams password reset email feature breaks! They have absolutely zero customer service also.

There's an option to disable your email just through your email
