I'm content to allow it. But only once, and only you, and only during a very brief window.
The reason I qualify this is to avoid commercial AV spammers from posting for the sole purpose of giving away trial keys to their software. To big software, Tom's is a goldmine of activity. Even giving away your product for free to our very large network of tech experts could result in a major boost in sales, because everyone here on Tom's is an influencer - so we have to be very careful about what we allow to prevent abuse.
