What are the legal risks of posting unauthorised promotional activity at transport hubs on social media?

Members discussed conducting unauthorised promotional sampling at tube platforms and the risk of posting evidence on Instagram. The key concern is visibility to transport authority enforcement teams (TfL in this case), which could trigger fines or enforcement action after the fact. **Key points from community experience:** - Members noted that they have "done outside tube stations before and never had a problem" — but crucially, they were uncertain whether they had "ventured onto the platform" itself, suggesting platform sampling is materially riskier than forecourt/external sampling - One member successfully avoided immediate fines during a platform sampling event, but remained uncertain about the downstream risk of posting photographic evidence on Instagram ("sense check we won't be walloped with a fine before posting") - The core risk is that social media posts create a permanent, searchable record that transport authorities can use to identify and fine operators retroactively, even if no enforcement action occurred on the day **Practical caveat:** Members did not provide a definitive legal answer or examples of fines incurred. The advice was largely anecdotal reassurance rather than legal guidance. Before posting, members should consider contacting TfL directly for explicit permission, or obtaining written approval from the transport hub operator — none of the excerpts mention this as a standard practice, but it would be the safest approach.
