    If you’ve encountered a message stating that you have been blocked due to suspicious behaviour, it usually indicates that you tried to perform a suspcious action on the site, which can be triggered either by the action itself, or the reputation of your IP address. 

    • Using a public VPN or proxy service: These services often share a single IP address among many users, some of which may be blacklisted.

    • Shared networks: This can also happen in environments like schools, offices, or libraries where many users access the site from a shared internet connection.

    • Certain words or specific phrases you are trying to submit to Flightsim.to are deemed harmful and triggering our firewall.

    What Can You Do?

    To resolve this issue, we recommend the following steps:

    1. Disable your VPN or proxy: Temporarily turn off any VPN or proxy service and try the action again. 

    2. Use your regular home connection: If possible, switch to a more personal or less-shared internet connection, such as your mobile data or home Wi-Fi.

    3. Ensure that your submissions do not include any specific phrases or symbols that could be considered harmful.
