Hot spots should only be shared privately to those you can trust.
General spots or locations might be able to be mentioned at times.
Posting false reports can piss alot of boaters off just like the dumping cereal in the water away from the action to attract birds and then attract the troops away from where you want to fish.
The worse thing about posting spots can be when masses of people show up and leave their trash all over and ruin it for everyone
Also too much pressure in an area can shut down the fishing.
