I'd love to see his actual dms. I used to help with an Instagram page for new mothers, it was breastfeeding help and the like, in my wheelhouse for work and I helped out while I was on maternity. Anyway, that page had around 100k followers and the whole purpose of it was for women to dm problems and someone would help. Even with that amount of following and the purpose being dms, the page got maybe 2-3 messages per day. Public page, no restriction on dm receiving. This is why I highly highly doubt that he gets dms daily, never mind be inundated with them. These people get far far less DMs than you'd think.
