Yes, I read Bandler and Grinder extensively and experimented with their techniques in the 80s, starting with happening across The Structure of Magic in the local university library, and ending, IIRC, with Using Your Brain For a Change, which includes transcripts from one or more of Bandler's workshops, and convinced me that he was a bullying fraud.
By then it was already clear that NLP concepts had no solid empirical or theoretical foundation and in any case did not improve my life in any way, but I was young and desperate enough for relief from the problems in my life that I held on to their promises way past any rational limit.
