The illegal part-time job has a back side, so you can't.

・illegal part-time job

「illegal part-time job」可以表達出「打黑工」的意思。「illegal part-time job recruited by antisocial groups online（反社會團體在網路上招募的黑工）」。

「有内幕」可以用「to have an ulterior motive（有不可告人的的目的）」去表達。「打黑工都有內幕，不建議嘗試」用英語可以這麼說。
I am against you will be engaged in an illegal part-time job recruited by antisocial groups online because it should have an ulterior motive.
（我反對你從事反社會團體在網路上招募的黑工，因為那些黑工都有內幕。）

用英語可以這麼說。
