There is a good deal of concern for all on a TG/TS site whether they are trans or cis. Sometimes, I wonder who's really the braver, us or cis-people like you (and a few others here) who befriend us.
As for the individual that sent the PMs out...I seriously doubt s/he considered or even cared who s/he PM'd. Some of them go thru the member's list and PM people who've been inactive - I've never understood the purpose in that. About the only good such PM's have done as far as I know was to cause long inactive members to drop in.
Some of these spammers target active people...most likely because they figure their spam is sure to be received, and in turn the chances their crap will be read.
Then of course, there are some that simply lump us in with all the adult/porn sites out there - we are compared to and considered no different than those in the sex trade. Therefore, again...no reason to consider whether a person is male, female, trans, cis, gay, or anything else.
Thanks for understanding, Del. PM any one of us anytime there is a problem.
