Once enabled, Telegram's native antispam system will start monitoring the supergrup, automatically deleting spam messages using the official Telegram Antispam bot, with ID equal totelegram_antispam_user_id, as specified by theclient configuration parameters.
Note that this botdoes not have to be added as participant or admin to the supergroup for the native antispam system to work, just invokingchannels.toggleAntiSpam is enough; however, it should still be locally shown as a group admin when displaying the admin list to the user (clients should simply append it to the admin listwithout invokingchannels.editAdmin).
False positive message deletions can be reported by admins by navigating through theadmin log, and invokingchannels.reportAntiSpamFalsePositive for mistakenchannelAdminLogEventActionDeleteMessage events made by thetelegram_antispam_user_id bot.
