I can't make an introduction post as it's saying it's being blocked as spam.
"Your submission has triggered the spam filter and will not be accepted. If you feel this is in error, please report that you are blocked."
It's odd that I can post here but not to the introductions.
Try again, you are clear now.
It likely had something to do with the content of the post rather than the location. First time posts containing multiple links, for example, tend to make the spam filter anxious.
