When a user sends a sticker, the bot extracts its emoji and adds it to a per-user sticker set named <user_id>_by_<bot_username>. If the set does not yet exist, it is created first. The bot supports regular, mask, and custom emoji sticker sets, determined by the type of the first sticker added. Sending /delete removes the user's entire sticker set.
