Apologies for the inconvenience and many thanks for isolating the problematic text! This is triggering a false positive for a security feature; we’ll get that fixed up.
There are some editing restrictions for brand new users who start at the lowest trust level when they initially sign up. Unfortunately we have to mitigate persistent spammers who try to sneak in dodgy links.
Note: you can flag posts for moderator review if there are inappropriate links, serious formatting issues, or other problems like off-topic discussion that need attention.
Regards,
Stennie
