I disagree, in fact I expect the fact that reporting is designed to take more effort than is usual in such an environment (when, as we see from the "report RMT activity" button, the facility for it not to in other cases is certainly possible), is a deliberate and intended feature, especially given the way Square Enix handles reports.
Remember that all of your reports in this game are reviewed by a human. None are rubber stamped by robot that I'm aware of (with the possible exception of the use of profanity - I'm still not sure on that one because I've heard from buds that they got suspended in far too short a time for normal human review, suggesting that reported chat logs are pre-scanned for profanity violations and if it's found are subject to summary judgment without need for a GM to confirm).
Also that compared to almost any other gaming service, you descend the penalty volcano at a glacial pace (in fact, you used to not be able to descend the penalty volcano at all, practically speaking), so reports actually actioned affect the person's status virtually forever (on a video game timescale).
As a result, a reporting system that forces people to be more sure of themselves before submitting, rather than make it easy for rage reports to be made, is virtually essential. Otherwise, the work load will probably become too much for SE to handle economically in a timely fashion, which will more than likely result in the situation you see in most other games (where the substance of the report virtually no longer matters, and account action is taken based almost exclusively on the number of reports someone receives - a situation which can be and in fact is heavily abused by bad faith actors, sometimes - see for instance the Ahn'Qiraj gate event in WoW Classic - to the point of virtually becoming a gameplay mechanic rather than the customer service tool it is intended as).
