Suggestion:
I want to be clear and simple!
Some people are spamming corporation invites to people without a corporation.
I am urgently requesting an option to block or prevent such invites from being sent, if I desire to do so!
Saying “NO!” apparently doesn’t help!
Ignore list with the sender’s name is not exactly a resourceful option to avoid this issue.
It’s time to have an option to check or uncheck - ‘Accept corporation invites’.
