Dear Wasleys,
Upon receiving your five infraction points, I immediately reread the forum rules and now I confess that I break the rules.
However, psychologically I feel a little unfair on my issue. In the thread where I did my improper post the OP asked "Do you have a company that you trust and could recommend?" for proofreading service. I was stupid enough to give him a direct answer and got the five infraction points.
I feel unfair for two reasons. First my motivation is good. I know the importance of proofreading in the application for PhD in economics for a non-native speaker because I am a non-native speaker myself. I am sympathetic about the OP's problem and I am willing to share with him my own experience in solving the problem.
Second I feel like falling into a trap: anyone who directly answer the OP's question will break the forum rule because he asked for a trusted brand name for a kind of service. Unfortunately I am the only person who fell into that trap.
I'm just complaining and I have no intention in challenging your authority in giving me the five infraction points.
Best
