Cannot create a group and invite friends to the group

Question

I was testing PushMessage to send message to a group if EventTypeMemberLeft triggered. I invited a friend and asked him to left the group to check the response I got. I did it many times (joining and leaving group). Now my account cannot create a group or invite anyone, including the bot to the group. Is my account getting limited? If so, how long do I need to wait to have my account limit lifted?

These are similar issues, and no solution provided.

I think my issue is related to Messaging API. It happened right after I tested my bot to send message to the group when someone leaves the group. Probaby my account is getting limited because of [this](https://developers.line.biz/en/docs/messaging-api/development-guidelines/#prohibiting-line-platform-load-tests)  

EDIT:
I contacted LINE support, asked why I can't create a new group or invite friends. They said my account is temporarily suspended due to activity that violated their Terms and Conditions of Use. They don't disclose which rules I violated. I suspect this one [this](https://developers.line.biz/en/docs/messaging-api/development-guidelines/#prohibiting-line-platform-load-tests).

How long do you need to wait?

I think this site is a developer community site, and it's not a site to share the LINE app issue. I'm sorry I'm not sure where to report it.

Hi ksyt, thanks for your response. LINE Messaging API tag removed.

Could you please tell what topic it is or have any insight regarding this issue?
