You are correct.  The parser uses so little resources I can run it on a free AWS server, so I could have an unlimited number of them.  But I don't want to overload the forum or risk getting banned - without Theymos' cooperation BPIP would not exist as it does now.  On the flip side, I wonder how much I am helping the forum by reducing people's research time and page views. 

As you can tell by the last parsed dates on a lot of reports, BPIP is doing a good job of keeping data in "near time".

I project that once I am parsing posts as well, I will need a maximum of five parses a second.  I'm sure this forum can handle that.
