I am still out of the country visiting family so all that follows is strictly my own opinion, as I have not had the opportunity to speak with any major Rabbanim about this. First let me state that what Rav Elazar Abuchatzeira is accused of is very serious. I personally do not know if the accusations are true or false. It is clear that people gave him large sums of money, whether that was done with specific promises of reward is what is unclear. In the US a person is supposed to be considered innocent until proven guilty, so for now, as I have not myself seen any evidence, I am going to remain neutral on his guilt or innocence.
Even if he did do what he is accused of, I doubt that it will be criminally prosecutable. On account of the US separation of Church and State, as well as numerous other factors, the case will very easily be made into a trial of religion and religious beliefs as well as the validity of certain religious claims. I am no lawyer, that is just my own personal assumption. My guess is that this will turn into a circus making Judaism look bad before this is all over.
On to the actual accusations. Again I am not implying either his guilt or innocence, I am strictly dealing with the "claims" he accused of having made. Simply speaking anyone making the claims that he is accused of having made, should be viewed as a charlatan. This is a mainstream Torah view, it was the view of Rav Kaduri, and it is the view of Rav Yaakov Hillel as he expounds in his book Faith and Folly.
First and foremost mekubalim through the ages have condemned the practice of "selling" spiritual remedies. In all of my time with Rav Kaduri, I never once saw him demand payment of any sort for prayers or segulot. If people would offer to pay him for a segula he would say, "Better that you give the money to tzedaka and ask HaShem in its merit for your need." Often people would try to pay him for prayers or segulot and he would always tell them that it was not necessary, specifically he would say, "Not necessary, not necessary better that you give to Tzedaka." Yes many people then put what they had wanted to give into the Yeshiva tzedaka box, however, he at least attempted make a distinction that he was not praying for them so that they would give him money. The Baba Sali, on several occasions was offered money to perform a segula/tikkun or to give a blessing, on every occasion he refused and threw the people out.
Secondly is the issue that has been brought up in numerous times in the news reports about influencing mazal. The Gemarra Shabbos 156a states, "Ain Mazal L'Yisrael", meaning that these things have no control over Yisrael as Jews are governed by Hashgaha pratit. I know that there is some back and forth in the Rishonim regarding this, however(and forgive me for not remembering the exact source) the Shulchan Aruch in Hilchot Avodah Zara quotes this exactly as halacha. Bearing in mind that Rav Yosef Karo was a talmid of both of the RaMaK and the AR"I, if there was any dissension about this thought, even among these great mekubalim, there would have been at least a Yeish Omrim. Meaning that there are other opinions, which while perhaps valid, are rejected by the Shulchan Aruch. For a full treatment as far as what we can look to mazal for see Shulchan Aruch Yoreh Deah 179. Even there it states only so that we may know what deficiencies in middot we are born with so that we may do the proper tikkunim within ourselves.
True mekubalim, true Kabbalists, have never sought monetary reward for even genuine segulot and tikkunim. True mekubalim strive to hold by every word(usually in the strictest manner) of the Shulchan Aruch. Therefore anyone who seeks monetary gain through hocus pocus which the Shulchan Aruch says does not affect the Jewish people is by all means a charlatan.
It is clear that there is a spiritual awakening of sorts taking place and that on account of that many people are drawn to spirituality. Within Judaism that is often Kabbalah. However, folk religion and superstition as well as actual chicanery is often passed off under the guise of Kabbalah. This is not something new, nor is it something for which the Rabbanim of the mekubalim were not prepared. I would strongly suggest that anyone who is thinking about consulting with a mekubal in any way over any issue first obtain a copy of Rav Yaakov Hillel's book Faith and Folly and read it several times. Its very purpose was to arm the average Jew with the necessary knowledge to be able to indentify charlatans and to steer clear.
I wish to reiterate that I am making no statements as to the guilt or innocence of Rav Elazar Abuchatzeira. I have not seen the evidence directly, and so I cannot say. My only point here was to definitively state that no true Kabbalist would ever do the things that he was accused of.
