lukaszraczylo 1ff26006f7 chore(examples): use api.Ptr for optional pointer fields
Replace the throwaway-local-var-then-take-address pattern with
api.Ptr in the polls and moderation examples. Net effect: 14 lines
gone, the pointer wrangling no longer steals visual focus from the
actual API call.

moderation

Group moderation commands: /kick, /ban, /mute, /warn, /unwarn.

What it shows

  • OnCommand for each moderation action
  • api.BanChatMember / api.UnbanChatMember for kick and ban
  • api.RestrictChatMember with ChatPermissions for muting
  • errors.Is(err, client.ErrForbidden) to surface missing-permissions errors cleanly
  • In-memory warn counter via sync.Map (auto-bans at 3 warnings)

Required bot permissions

The bot must be an admin in the group with "can ban users" and "can restrict members" permissions. Without those rights, commands will reply with a friendly error message instead of crashing.

Usage

All commands work by replying to a target user's message:

/kick   — remove from group (can rejoin)
/ban    — permanent ban
/mute   — silence for 1 hour
/warn   — issue a warning (3 warnings = auto-ban)
/unwarn — remove the last warning

Production notes

  • The warn counter is in-memory and lost on restart. For production, back it with Redis or a database.
  • Consider adding an admin check (see examples/admin) so only group admins can invoke these commands.
