I don't understand why many users take it as normal because the past was different than now. Most of users in the past are spamming by creating one liner post without any point and it's still exist until now, if it should be deleted maybe 50% of total posts in this forum will be deleted.
If I'm not mistaken buy and sell Bitcointalk account in the past doesn't have any problem too.
Another thing it's fine for DT members were left negative feedback because of spamming and merit abuse, if you do it now don't be surprised if someone will create a thread in Reputation and you will be excluded from DT system.
Also its not just about your message maybe some threads itself got deleted which included our post too.
If the thread got deleted, the @OP wouldn't get email notifications.
But if the thread is self moderated and he deleted @OP post, @OP will get notifications.
