if you want to keep your anonymity, don't bring it up lol
you can talk about your job and what you do, without mentioning all the connections and people you know, without actually mentioning them.
honestly, if i didn't want people to know i was a high class supermodel, the first thing i would do is never talk about it.
as for the movie of your friend's, nothing at all wrong with supporting a friend. had you said that from the get-go i bet you would've actually gotten a much more positive response. so i hope in the future should the opportunity arise, that's the way you would approach it rather than the way you did.

to all of this.
I'm a member of a forum where some people are pretty big names in their field, or are officials or are even related to the people we discuss. NOBODY says ANYTHING about what they do or who they are. I mean, we do have one guy who we know is an official, because he uses his real name as his username.

But otherwise, nothing. Bupkiss.
They know that talking about their work (whatever it is - we have lawyers, policymakers, designers, professors, doctors, I even met my Hollywood sound mixer friend from this forum) can come back later to bite them in the ass. They
do not talk about their work in any sort of detail. They can display their knowledge when the subject comes up that's related to their work, but no way do they get into specifics.
Now, all of these posters (including me) are older than you Ultimatehero, so maybe you just haven't been burned yet. But posting about what you, as an aspiring film screenwriter, are doing in any sort of detail on a forum whose main subject IS movies....I'd be very
very careful about what I share.
I live in LA. A number of people I know are aspiring screenwriters. (A friend of mine even gets paid to write, and I've met a few writers and actors that people here have probably heard of.) But
none of them do what you are doing on this forum. That's why you're such an easy target, because nobody else is offering himself up like this.
And yeah, seriously, if you had a friend who wanted people to know about his movie, it would've been best to be upfront about your connection. The way you went about it made you look like a spambot.
