No, because messages have a TTL precisely to avoid continuously flooding of the entire network, or messages looping, etc. Without this, all the links would quickly become saturated, as would the caches, and the network would collapse.

Ideally, the TTL should be as low as possible in order to preserve maximum bandwidth and not hit nodes far from the transmitter.

The Bitchat documentation indicates that the maximum TTL is 7. There is also mention of gateways on the internet to enable long-distance communication.

In the case of IoT devices, their location is generally fixed and the gateway or hub is placed in the centre in order to limit the TTL, save bandwith, limit wakeup time. Some more advanced mesh network protocols use flooding only for announcements and network mapping in order to avoid this problem. This allows it to define preferred routes, set up an acknowledgement system, replay, etc.
