my account will be remove after How many times item rejected?
Your account won’t be removed just for having items rejected.
This would only happen if you were to repetitively break the rules
What is the rule Can you tell me?
Don’t resubmit previously rejected items without significant changes
Don’t rip off other peoples’ design or code
If an author then don’t buy your own items or create fake reviews
Etc etc
It’s simply all about behaving with common sense
