Growth...it is a super wide concept you can take or interprete in many ways here. I´m devoted to Web3 spaces so from my POV there are many aspects you can apply there that can also be applied here like growth strategies:

(DEV+UI+UX) Why not having separated or dedicated spaces for international communities like different language lounges?

(DEV+UI+UX) Why not translating SN to other wide used languages like Spanish? (i am a native spanish speaker btw)

(SOCIAL) Quality posting on a daily basis in Twitter could improve the reach of SN and bring more people to join

...and many more.

"Proper" is something i think could be a fit applied here from my very own POV as Growth guy but you, from your very own POV could not see as a nice choice to go for.

Growing is not only opening a Telegram chat and pay some weird guy to run a bot and bring 10K vultures that do not care about you or what you do (this is also growth btw...i do not like it, but usually done to improve numbers for investors ;) ). Properly growing is to identify actions that could help you get more visibility, bring more users and turn your product into something viable, usable and widely known for EVERYONE
