Just a quick question on the original post. 'Rudy' is a man's name, usually short for Rudolph. Did this chatty guy tell you he was a guy or a girl? Or just imply it?
I don't have a problem with my bio or email or address or whatever on my company website, but I would surely avoid offering anything in the way of financial information, or membership in sites which would imply you have an interesting amount of liquid assets waiting to be exploited.
I think that 'liking' products is free advertising plus free marketing info for the manufacturers and on that basis alone should be avoided!
Thanks for posting. You might try one of those companies which purports to 'scrub' or delete your on-line info which you no longer want on line.
