I got the PM this morning, unknown member with an unfamiliar (not rocketry related) message title, checked the day "it" joined, copied the link and googled it... google results had no "cache" version of the website and there was a wide variety of topics so I decided to just delete the message without clicking on the link...
Advise for all: If it comes from someone you do not know with a weird or unsolicited topic, google it or just delete it and keep going with life...
