Spam filtering app

Good day.
Read bellow BEFORE bidding...

Looking for an Android app to be made that filters any keywords you want from incoming dms on instagram or any other similar platform (screenshots of examples are included).
- Most importantly : I want to see proof you have made an app that still works and is being used (Include links with the app being used by people, or with the app itself).
- Bids without the above rule will NOT be entertained...!
- Must be able to work with dms from strangers, not only people you follow or follow you.
- Must work for every message they try to send, not just the first one.
- User must be able to input the words he doesn't want to see (obviously).
- Message can be hidden or blurred, but preferably, not even received in my dm inbox.
If you've read untill here, and understand what is required, drop a banana emoji at the top of your bid.

Thanks.
