Seriously it is beyond ridiculous that mydramalist makes it possible to leave review after the first episodes.…
Nothing wrong with writing a first impressions review. It does show in the review section how many eps the reviewer watched before making the review so any reader can judge for themselves as you have if the review is fair. However superficial you find BL Compilations' review it's their honest opinion on what they have watched so far and it's as valid as anyone else's. Some members on the site actually like to see those types of reviews. If it's not something that will immediately grab them in the first 1-2 eps they are grateful for the heads up so they won't waste their time.
My only advise is that the reviewer should point out in the review how many eps they've watched all the same. Also if they continue watching the series to remember to revise the review.
As long as the reviewer is being honest not malicious or disrespectful it shouldn't have to be their concern if it drives people to or from the drama they are reviewing. I don't see any reviews for the series so I guess the reviewer was sufficiently intimidated to remove it. Congrats.
