A mazloom, is for looming into cases, where tyrants and/or agent-provocateurs abuse the people. The mazloom rule-of-thumb is to do-the-right-thing[-and-get-hurt]. A mazloom, normally, would loom at reported trouble spots, to have armaze timely intervene. Otherwise, most offenses would be left to guesswork at courts -- unless the aforemaze data on the record, is really enough to investigate, for finding out who was the offender/guilty.
I differentiate the two, mazloom and mazlum (read both, maz-loom), the latter the normally-oppressed, whereas the mazloom is the active-actor/actress who is getting into where people are hurt, to help those mazlum-people. To define the "loom" (from the Macmillan Contemporary Dictionary), I may relate to a mazloom, as
enough? The information-recorder is a force-framework (most expectably, the frightened) watching the case, while the mazloom is in -- for acting, and probing the case in real-time, to ensure that a punishment is due.
The amount, and fine-level/range of the anticipated encounterable case-varieties (while a mazloom goes in, for information-retrieval), may vary widely, and thoroughly studied with the armaze/frightened, while getting ready.
If people would wrongly think of a mazloom as only a "spy/agent," that would only mix up all the spy categories.
e.g: The FBI spies, go join the suspects, and third-people would think of them as if they were really guilty people. Not so in the case of a mazloom -- who is as if the ordinary victim, not the suspect. Even if/when a thousand different armaze/frightened/etc people may have sent in, a zillion mazloom people in, and if any of those (a thousand) frightened/etc people, may find that enough (resolve for the next-phase), no other mazloom working for any other force, would get hurt, as they are all, noticeably innocent. In the FBI case though, that spy who is seen as the "MAFIA-aligned thief/etc." may be in the target-list of some other law-enforcement agency.
Agent-provocateurs urge crowds to anarchy, try to provoke a victim to target another, etc. -- to let some tyrannical-and/or-corrupt states/groups benefit out of that turmoil, and/or to crush the victim/mazlum people.
In contrast, a mazloom is resembling a regular mazlum. Entering the scene (if not already a resident, real mazlum, there), where other people were (inconclusively) reported to have lived under oppression. The aim is to clarify the case. The tyrant crew, is put into a test-situation. e.g: If a case surfaced, the mazloom may tell them that they do wrong, or explain what was right to do. Normally, such a well-thought warning was supposed to end the offense. In most chronic cases, though, that may only fuel the hostility of the evil crew. Those are what, the armaze/frightened people reflect (in real-time), and they are there to react, when the information is enough.
