Why is 'used to troll' a potentially bad keyword? [closed]

CharcoalHQ caught a post about appealing a network wide ban on Meta.SE yesterday.

Potentially bad keyword in body

The bad keyword is apparently 'used to troll.' What's toxic or potentially bad about 'used to troll?' Can someone explain why this is a blacklisted keyword?

Also this question was caught by CharcoalHQ just now.

Solution 1:

There's nothing inherently offensive about the phrase "used to troll". What is being expressed is that a specific keyword (unstated in your question) is commonly used in the activity of trolling.

Wikipedia describes trolling as

In Internet slang, a troll is a person who starts flame wars or intentionally upsets people on the Internet by posting inflammatory and digressive,1 extraneous, or off-topic messages in an online community (such as a newsgroup, forum, chat room, or blog) with the intent of provoking readers into displaying emotional responses[2] and normalizing tangential discussion,[3] either for the troll's amusement or a specific gain.

The word or phrase that got "caught" by the algorithm was one that apparently appeared commonly in messages from trolls and less common in "legitimate" messages.

Merriam-Webster also provides a definition of trolling:

2a : to antagonize (others) online by deliberately posting inflammatory, irrelevant, or offensive comments or other disruptive content
