I am seeing it repeatedly on the forum. I think it is cowardly.
Sometimes it is appears in the form of accusing others of behaving like JW elders. To add insult to injury, it is frequently used by some who were never JWs.
Consider what many of us had to go through to get out the cult - what is cost us in terms of family and friends. The intellectual struggles we experienced to get over years of indoctrination. The courage and integrity it took to reject everything we once held dear.
To label somebody who disagrees with you as acting like a JW is a craven personal attack.
There are occasions when it is simply a statement of fact - when somebody preaches end-times speculation for example - but to use it as a cheap shot is unacceptable.
