[IT] If nobody outside of the Losers Club knew about Pennywise, then how did they explain the massive spike in child disappearances/deaths that happens every 27 years?

They didn't. 

Pennywise's influence causes people to overlook shocking violence or other things that are wrong. Since Derry was such a nowhere, most outside reporters wouldn't even take note of it (and no internet so you'd have to do a little digging if you wanted to know it in the first place). 

Lots of disturbing things happen in Derry and people take them in stride. Factory explosions, dangerous cults burning down buildings, etc.
