Thank you,  @David-TP 

Is the new device operational until blacklisted? Unfortunately I work 10-12 hours a day and commute for another 2, while a teenager has infinite time. Outside of hiring an L1 support team, as a parent I don't think I stand a chance of blacklisting a device every time a new MAC is spoofed. Or did I misunderstand how blacklisting works?

If my understanding is correct, do you think the feature request has any chance of making a backlog anytime soon or should I invest in a new network device rather than wait?

Mobile device connected to Deco mesh will be operational until it is blacklisted.

I would recommend investing in a new network device(s). The topic of MAC address randomization bypassing parental controls was raised with TP-Link in 2021, but there is no reply if and when that will make into firmware. Next firmware (ver. 1.6), which is currently in beta, targeting M5 now and M9 Plus in the future, does not have that functionality. 

If you have multiple Deco M9 Plus, you could reuse them in Access Point mode with the router (wireless or even just wired) which has strong parental controls and can deal with MAC address randomization. 

Otherwise, just replace Deco with some other brand.
