About Daysandbox Bot

Daysandbox Bot is simple yet effective anti-spam bot. The idea is to delete links, media 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. You can set list of domains and groups/channels which should never be blocked. You can add new member of chat to whitelist if you want to allow him to post links before safe period expired. Deleting media messages is disabled by default, read Commands to see how to enable removing media messages from new users.

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.
• message contains button of any type. Usually such messages are posted via inline bots
• media messages, disabled by default. Media are audio, game, animation, document, photo, video, voice, video note, contact, location
