Key points
- Blocking ends contact entirely. That works only when you never need to hear from the person again.
- When you must stay reachable (children, a legal matter, a business relationship), blocking can backfire and cost you information you needed.
- Filtering keeps you reachable but removes the hostile content before it reaches you, and keeps a record of everything.
- You can always read the unfiltered original if you want to; you are never forced to.
A friendly note: This guide shares general information to help you understand your options. It isn’t legal advice, and it can’t tell you what to do in your own situation. For that, a lawyer or a free legal service is the best next step, and you’ll find some in Where to get help.
When someone’s messages become abusive, blocking feels like the obvious answer, and sometimes it is the right one. But blocking is all-or-nothing. It ends the channel completely. If there is any reason you still need to receive messages from that person, blocking creates new problems while solving the old one.
What blocking does well, and badly
Blocking is simple and final. If you genuinely never need contact with the person again, it is often the cleanest choice. The trouble starts when contact has to continue. If you share children, have an open legal matter, or run a business the person is a customer or supplier of, going silent can mean missing things that matter to you: a change to a pickup time, a deadline, a payment, a notice you needed to act on. Our guide on how to stop someone texting without blocking them covers those situations.
Blocking can also be read against you. In family and some legal contexts, refusing all contact can be characterised as uncooperative, even when you are doing it to protect yourself. And a determined person simply switches to a new number or address, so the block rarely holds.
What filtering does differently
Filtering keeps the channel open but changes what comes through it. Each message is processed by AI, the hostile or manipulative content is removed, and the useful part is delivered to you. You stay reachable for the things that matter without having to absorb the abuse wrapped around them. You decide when to read, rather than being interrupted by a hostile message the moment it lands. See how to filter abusive messages with AI for more detail.
You keep the evidence either way
One hidden cost of blocking is that it can destroy your record. With FenceChat, every message is stored, original and filtered, with a timestamp. So filtering does not just spare you the hostility, it quietly builds the complete record that blocking would have thrown away.
You are always in control
Filtering is not censorship of your own inbox. The unfiltered original is always available to view if you choose, and you decide who can reach you at all. With FenceChat only the contacts you add can message your FenceChat number, so strangers and spam are out entirely, while the people you must stay reachable to come through, calmly. See how FenceChat works for the full set-up.

Frequently asked questions
Is filtering better than blocking?
Neither is universally better. Block when you never need contact again. Filter when you must stay reachable but want to remove the hostility and keep a record.
Will the other person know they have been filtered?
Not for any individual message. The filtering happens on your side and nothing marks a message as altered. They do receive one notice the first time they contact you, saying messages are processed by AI and stored. After that, the only sign is a short “Sent via FenceChat using AI” line on messages you send through FenceChat. It can be switched off where telling them could put you at risk.
Can I still block someone inside a filtering service?
Yes. With FenceChat only contacts you add can reach your number, so anyone you do not add is effectively blocked, while approved contacts are filtered.
Does filtering keep a record like blocking destroys?
Filtering with FenceChat stores every message, original and filtered, with a timestamp, so you keep a complete record rather than losing it.
What if a message is genuinely urgent?
Useful and urgent information is preserved and delivered; only the hostile content is removed. You can also open the original at any time.
