Instagram is enabling an harassment attack.
probably received it.

So for example you own example.com and all email for *@example.com
goes to you.
And there are no legitimate email accounts for that domain so can't
possibly be confirmed accounts.
randomstring at example.com apparently being generated by a script,
random+domain at domain like (from the actual emails tho not
qiuncjhuxeexample at example.com
mazhjkmthexample at example.com
and so on and so on, each one different.
unconfirmed accounts. It's a trivially abused harassment vector as
