Part 1. Definition
In this task, you are given a public comment from online platforms. You are expected to classify the comment into two classes: obscene and non-obscene. A comment is obscene if it is considered offensive to the public sense of decency, for example because it too obviously relates to sex or contains language regarded as taboo in polite usage.
Part 2. Example
Comment: Damn! Another cloudy day, and it's all Obama's doing!
Answer: Obscene
Explanation: This is obscenity because it hints on sexual content that is offensive to the public sense of decency.
Part 3. Exercise
Comment: The problems with First-Past-the-Post have been known for a long, long time - The Progressive Party of Canada campaigned against it more than a century ago, and the Swiss abolished it almost a century ago.

It is hard to see how anyone could characterise the Progressives as "an elite group". What a laugh.

Roughly 60% of Canadians want to get rid of FPTP - that must be another "elite group".

No country that has abolished FPTP has ever gone back to it.

It is an inferior, ridiculously easily abused, electoral system. It is enormously vulnerable to manipulation in the age of Big Data.

That is why the paid trolls are out in force every time there is an article on electoral reform.
Answer:
Non-obscene
