How to block specific words in a Telegram group
SpamFixer lets group owners create custom banned words and phrases. Messages are checked automatically, including edited messages.
Set up banned words step by step
2. Open SpamFixer privately
Open Protection → My Groups.
3. Select the group
Open settings for the group you want to protect.
4. Open Banned words
Enable the filter and choose Add rule.
5. Send a word or phrase
A single token is stored as a word; multiple words are stored as a phrase.
6. Choose the scope
Apply the rule to this group only or to all groups you own.
7. Test it
Send a test message. Edited messages are rechecked too.
Why custom rules matter
Global anti-spam catches common spam; custom rules enforce the vocabulary of your own community.
Words and phrases
Multi-word input is stored as a phrase. Specific phrases usually reduce false positives.
One group or all owner groups
Group scope is local. Owner scope applies the rule to all active groups owned by the same user.
Edited messages are rechecked
Posting clean text and later inserting a banned word by editing does not bypass the filter.
Rule quality
Avoid overly broad short words unless they are truly forbidden.
