Why was my account disabled?

Hi, My Snapchat is not deleting  Please help.

Hi,

I help run an instagram account for our company (DeepGameBasketball). We typically are only following 1 person (Kobe Bryant). However, every few weeks there seems to be someone else who is added to our "following" list. Our (few) team members have confirmed they haven't been doing this manually. Could there be some sort of reason/glitch to explain why this is occurring?

Our account is not connected to any third party apps.

Best,
Coach S.

Hello,
How to recover my Facebook account. Disable ineligible issue

Hello,

I've been emailing an account that I know is active and it's a address that receives alot of public emails. I've been emailing for years and not always receiving a reply. However for the first time, this morning I sent an email received the 554.30 reply below. I know the account is busy and active normally until this morning. Can this mean they blocked me? Can this mean their inbox was full and could not receive any incoming mail at that time?

Your message wasn't delivered to ***@*** because the address couldn't be found, or is unable to receive mail.

The response from the remote server was:
