Profanity filter

Tip: change one option at a time and verify the result in the group so false positives are easy to spot.

In short#

The profanity filter combines a system dictionary with optional custom words and exceptions for group-specific language.

How it works#

1. The filter checks text and supported media captions against the selected dictionaries.
2. Exceptions and custom words change which matches are considered violations.
3. Edited messages are checked as well; a violation then triggers deletion and the selected action.

Set it up step by step#

1. Open Defendy in Telegram and choose the group you want to configure.
2. Compare the current values with the defaults explained below.
3. Change one option at a time; use the least disruptive value that meets your goal.
4. Check the result in the group after saving.

Every setting explained#

Enable filter#

Default: Off.

Turns profanity detection on for the group.

Dictionary mode#

Default: Combined.

System dictionary, custom dictionary or combined mode.

Filter media captions#

Default: On.

Applies checks to media captions.

Filter edits (always on)#

Default: On.

Checks edited messages after they change. The WebApp shows this as always on without a switch.

Delete message#

Default: On.

Deletes a message when profanity is detected.

Action#

Default: Nothing.

What Defendy does after a violation: nothing, warn, notify, mute, kick or ban depending on the feature.

Action duration#

Default: 3600 sec.

How long a temporary mute or restriction lasts. Zero usually means no duration or permanent action.

Warning weight#

Default: 1.

How many warning points this violation adds to the warning system.

Exceptions#

Default: Empty.

Words or phrases that should not trigger the filter.

Practical example#

Choose the combined dictionary, add an innocent product name to exceptions, and use warning weight 1. Test the word in plain text, a caption and an edited message before rollout.

Recommendations#

• Use exceptions before switching to stricter actions.
• Custom dictionaries are useful for local slang, product names and false positives.

Troubleshooting#

• Check that Defendy is still an administrator in the group.
• Refresh the settings panel and make sure you are editing the correct group.
• If a setting is saved but does not work, check the bot permissions in Telegram.
• If you are not sure what happened, open the moderation log.
