There is a kind of fine line. I think going to the grave of Reb Nahman to say the ten psalms is fine. But just that one can step over an invisible line.
But the whole going to "kivrei tzadikim" [grave of the righteous] has gone way past the fine line.
However to a small degree it is allowed and even mentioned in the Gemara itself on as a practice that is legitimate.
In fact I noticed today that someone quoted the חיי מוהר'ן קס''ב [Life of Reb Nahman. 162] where Reb Nahman said that he wanted to return to Israel and to die there. That is he did not in fact want to be buried in Uman. Rather --if it had been his choice he would have returned to Israel and to stay there until he died and to be buried in Israel.
