Atomizer is a free to use Discord bot that can nuke channels. Basically, it clears all the messages in a channel, similar to purge, but bypasses the 14 day limit, and even users with modded discord clients wont be able to see them or log the messages.
Additionally, there are other basic moderation commands such as banning, kicking, purging etc, and other fun commands.
** This bot does NOT nuke servers. **
