Some write carelessly. Some write without spelling or punctuation or grammar.
Some make zero sense at all.
Those trolls are easy to ignore.
Other trolls are careful. Thoughtful, even.
They write in perfect grammar. And they appear worthy of your time.
The sophisticated trolls.
Then there are the non-trolls. The people who ARE worth of your time.
It’s tough to tell the difference between the sophisticated trolls and the non-trolls.
When in doubt, though, they’re probably just a sophisticated troll. And thus, not worth your time.
