Flags — countries where our network of observers on Telegram recorded this ad being shown in this channel. It's not the advertiser's targeting country: Telegram serves sponsored ads worldwide, and we simply note where the ad appeared in the feed. The channel's main country (by its language) is highlighted in blue; rare placements (under 5%) are collapsed into “+N”.
