Works great. You must enable ‘Filter Unknown Senders’ and add numbers you trust to your contacts. I use it to block incessant political campaign spam texts.

I’ll give it a go! It’s not very counterintuitive though! Any tutorials out there?

We have put several keywords into “blacklist” that should block texts that come in using any of those words, and yet texts are still coming through with those exact words in them. This is precisely what the app is designed to prevent.

So far, I have tried to give it words to blacklist and when I have had people try texting me using those words the text still comes through. So either it isn’t working, or it isn’t user-friendly enough for me to be able to figure out how it works when it looks like I am doing everything right.

I have had this app since the barrage of pain in the a** robo-calls and texts began and it’s still the only app I’ve found to successfully block the annoying repetitive useless texts that are funneled to my phone on a daily basis. The app does have a learning curve to it but that’s necessary in its function. Take the time to search for the info available on the web and learn how to use it. If I’m not mistaken there is still some info on GitHub. This app is probably the ONLY app out there that gives you COMPLETE AUTONOMY over who and what can text you. One of the best features is being able to block blocks of numbers. If your number is (123) 456-7890 you can block all numbers starting w/ (123) 456- as a block so those spoofing 123-456 trying to get you to think it’s a legit call will not interrupt you at 3 am or while you’re working etc. You also have the option of blocking words individually or in groups. So when the date online free messages start, simply plug in to block all texts containing date+online+free. This way all texts containing date or online or free will go through but if it contains all three words in the same text it will be sent to spam. I found that the first slam text typically is just the calm before the storm so I pick the keywords from it then create a filter and then the following 2-300+ texts to follow are blocked as are all the responses from the group text that were included with the original from people saying STOP or “quit texting me ^^#}~**#~🤬”!!!” Which is even more annoying than the original.

匹配规则的垃圾短信只是消除了通知推送,并被分组到“过滤短信”,但还是会显示未读角标,要点进去把垃圾短信读一遍才能消除角标,要疯
