the forkgram and mercurygram programs contain advertising in channels, bots, and search. this is not mentioned on the respective pages when downloading the software. for the sake of user transparecy, i think the anti-feature tag should be applied.
the developers of forkgram expressed that they are not removing the advertising to stay compliant with telegram’s terms in this issue.
the ads are added on behalf of the channel/bot owners through the telegram’s advertising network to users who do not have a subscription, not directly by the channels as a regular message.
