➠ Do stickers annoy you? or want to avoid people sharing links? or pictures? \
You're in the right place!
The locks module allows you to lock away some common items in the \
telegram world; our bot will automatically delete them!

» /locktypes: Lists all possible locktypes

➠ *Admins only:*
» /lock <type>: Lock items of a certain type (not available in private)
» /unlock <type>: Unlock items of a certain type (not available in private)
» /locks: The current list of locks in this chat.

➠ Locks can be used to restrict a group's users.
eg:
Locking urls will auto-delete all messages with urls, locking stickers will restrict all \
non-admin users from sending stickers, etc.
Locking bots will stop non-admins from adding bots to the chat.
Locking anonchannel will stop anonymous channel from messaging in your group.

➠ *Note:*

» Unlocking permission *info* will allow members (non-admins) to change the group information, such as the description or the group name

» Unlocking permission *pin* will allow members (non-admins) to pin a message in a group
