About Daysandbox Bot

Daysandbox Bot is simple yet effective anti-spam bot. The idea is to delete links and forwarded messages written by users joined chatroom in less than 24 hours ago. This technique allows to delete most of spam messages from new users. Downside of this approach is that any chat member older than 1 day can post anything. This is tradeoff between simplicity and efficiency. You get for free a tool that automatically removes lot of spam messages but not all of it.

Type of messages counted by Daysandbox Bot as possible spam:

  • message forwarded from another chat
  • message contains link to some web document
  • message contains @username mention pointing to a group or to a channel. If @username points to some user then it is not counted as link.


Follow these steps:

  • Add @daysandbox_bot as admin into your chatroom
  • Give bot a permission to delete messages. No other permissions are required


  • /daysandbox_set publog=yes - set bot to write messages into chatroom about each removed spam message
  • /daysandbox_set publog=no - set bot to remove spam messages silently
  • /daysandbox_set safe_hours=X - set safe period to X hours. X value should be a number in range 0 < X < 720. In other words, safe period should be grater than zero and less or equal to one month.
  • /daysandbox_config - display bot config for current chat
  • /daysandbox_check - check if bot installed correctly
  • /daysandbox_reload_admins - ask bot to reload admin IDs for current chat. Admins list is collected once and cached. Use this command to update cached data.

All these commands have to be entered in chatroom you want to configure (where bot is installed).


How to check if bot works?

First, complete installation instructions. Then type into chat this command: /daysandbox_check. Fix any issues bot talkes about.

Is it possible to make bot not delete posts sent by admin?

Admin can just wait for 24 hours and then post links. If you want to delete any link anytime from anybody except admins then just use WatchDog Robot

Bot does not deletes some spam

Bot deletes links only from new users. If user is in chat for more than 24 hours then bot will not delete any message from such user. Also bot does not process any message from users that were in the chat on the moment whent bot was added to the chat. This is because bot can't find out join time of old users, it can do it only for new users that join the chat where bot works already.

Bot does not work

It works. Every day @daysandbox_bot deletes about 50-70 thousand spam messages.

Bot banned some user in my group by mistake

Daysandbox does not log deleted messages to my channel
