enough spam in this world...

It sounds like the standard spam in the mail.

I doubt spamming people with the merits of BP is going to make you the kind of connections you are looking for.

A lot of list sellers sell and resell and by the time you get it the data is not only out of date but they have been pestered so much they do not want to know if they are not simply spam data copied off the net somewhere. 

You are spamming the forums. 

One was $49.99 and took years to get off their spam list.  

I post on Craigslist, Nextdoor, my work classifieds section, my college alumni classifieds, and sometimes facebook marketplace (but I get more spam and weirdos through that).

I've not registered my details to gain new information for a few years and i'm interested in seeing some fresh marketing.I've been through my inbox investment folder  (aka spam folder) for properties and investments and noticed I'm getting a lot less sent than I was a decade ago.

I was able to send two (or maybe three) but on the next attempt I was blocked for spamming.

After a month or two, I started receiving spam to those temporary e-mail addresses, so I deleted them.I hope this helps.
