If it is the OP that created the topic that deleted your post in his self-modertated thread, you will be notified on the forum.
I didn't know that we are notified when the OP deletes a post in a self-moderated topic, because I avoid self-moderated topics most of the time.
When you will not be notified is when the whole thread is deleted by a moderator or admin. You can use the
Bitlist.co Telegram bot for that.
I knew about this, but I am expecting something official from the forum. Even then, I didn't get notified on the Bitlist.co Telegram bot when
this topic was deleted.
If I may ask, why do you want to have a problem with deleted posts which have no notifications?
I wouldn't say this was a big problem to me, but I also think there shouldn't be any problem if I get notified if a post I made has been deleted indirectly?
Do you think, because it can reduce the number of posts for your campaign, if you don't realize it?
Those are just two questions from me.
Yes, this is another reason.

But I want to tell you, if in the end what you say is still unrealized, you can find it in the telegram bot @BTTSuperNotifier_bot
In the bot you will get a notification when your post is in a deleted thread, like the following:

Actually, I have been using this bot for a long time, and I am aware of its features, but this feature did not notify me of the deleted topic where I posted a few days ago, which is why I originally opened this topic.
