Almost three years ago, we had a question What is the plant tag used for? with a couple of answers saying plant isn't useful because it's too general — it can apply to every question on the site except those that aren't about plants — and should go away. At that time it was edited out of all questions that used it.
Since then, it was reintroduced and proliferated to over 30 questions (including a handful today). I've since edited it out of those questions, and would now like it blacklisted to prevent it from coming back.
As of March 15, 2019 there were a further 14 questions with it.
