Since you’re the admin, you have the final say, obviously. @maltfield is a fellow user of monero.town. Apparently their posts were well received once ( monero.town/post/478676 monero.town/post/132041 ) then became a bit too repetitive and (perceived as) spammy.

we should probably add something similar to r/monero where you can only advertise every 2 weeks as well as limiting reposts to your own community and a limited amount of others

Sounds reasonable.
