Connector packed with di-electric grease

Got this photo from a colleague who works in after-sales, an MC41 connector packed with di-electric grease.

The Molex MX123 is a sealed connector when properly assembled, so adding di-electric grease does nothing to improve protection against water and dust. Instead, it can only cause problems by getting in the way for the pins and prevent contact. 

I do not know how widespread this problem is. 

Do you guys also have problems with people putting grease inside the connectors? 

It is really difficult to find good service technicians nowadays, I have seen users putting rice inside electrical cabinets in an effort to keep moisture out, that in turn provides food for critters that like the warm environment...
