You have been blacklisted on your previous account and you will be on this one for systemic #introduceyourself tag abuse, copy/paste and spam.
Using irrelevant tags, especially popular tags, makes it hard to find good and relevant content. Please try to use only relevant tags when posting.
Please be mindful of topic-specific tags. These tags are for articles written in these topics. The introduceyourself tag is only for a person's initial introductory post on their original account.
