Found an interesting address ... looks like someone has been giving away $2.5million over the last 2.5 months.

They seem to like sending lots of single transactions to a set of addresses with the same first character ... very unusual

Some of it landed in the pool address just now.
Odd indeed.
Stranger now with the addition of the self-referencing link to this thread in the above-referenced address' referenced (mentioned) links. (Click on the link that Kano provided - this discussion is in the "Mentioned" list now.)
