They are about every 6 feet or so around the perimeter of the basement.
Its like when setting the walls they turned a set of blocks for some reason.
What I'm seeing now is, all of the bottom blocks are eroding, or disappearing around the corners. Water is then leaking in around the wall or these blocks at the bottom.
The guy who owned the house was a cement guy, I can't really say a good one because anything/everything I've found in this house has been a hack job. He did have edge drains done in the basement, but they don't work well since when it rains a bit, the edges at the floor leak.

Is it a pier..... is there a carrying beam above those blocks ?
A picture of the wall from floor to ceiling would help.

Ahhh..... you posted more pics while I was typing.

Could also be to stabilize the wall from lateral forces.

It is a pilaster (thickened part of the wall) for lateral wall reinforcement that is to allow thinner block in the wall itself. The penalty is the problems with interior finishing. - You probably have 8" basement walls judging by the 6' spacing), but in most areas 10" or 12" walls with very minimal reinforcement would give you a flush interior surface.

It usually in not a column because the vertical load on a basement wall from the exterior walls and roof is not enough to justify having pilasters. They are often located to take some interior beam loads for the first floor use and loads.

The moisture is from a lack of water control on the exterior and at the footing level. Interior and exterior drain tile usually handle the water, but apparently it is not functioning. The "edge" drain may not have been deep enough to collect the water.
