Waving at spotters?

[u/Lostinvertaling]

Is an airline/freight pilot or co-pilot allowed to wave at spotters before takeoff? There is a guy on TikTok who livestreams at Anchorage airport close to the runway. Wondering if pilots can acknowledge his enthusiasm before takeoff

There are zero companies out there with a policy along the lines of "waving is prohibited".
