Sifter - Spam SMS Filter

为啥要强制开启iCloud上传？不开启就不能用啊……

One of, if not the only app in the App Store allowing you to block those annoying, repetitive, unsolicited texts that are sent with click-bait links in hopes you’ll access a Trojan horse or other nefarious link. The “regex” area is a bit difficult if you don’t understand regex, but there are still several other ways to block these texts in bulk, the easiest being by copy and pasting +the+text+you+want+to+block in ⬅️ this format. Then all texts sent after that fit that format will be automatical

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.
