Some combinations appear in real text but do not mean what learners often assume.

Using by directly after exploit without a method

Exploit by usually needs an action or method after by.

Confusing purpose and method

Use for to show benefit or purpose, and by to show how something was done.

✕ They exploited the market by huge profits. ✓ They exploited the market for huge profits.

Adding an unnecessary preposition

Exploit can take a direct object without another preposition.

✕ She exploited on the opportunity. ✓ She exploited the opportunity.
