I was expecting something like that.
With regret, I have to admit that the Graviex Exchange has plunged into a banal financially-oriented cybercrime! Instead of returning the withdrawn funds (214 ARRR coins), Graviex blocked my account and seized funds of about $ 1,500 at the current rate, which the exchange itself admitted by posting appropriate posts on the resources:

To date, in order to avoid deleting or changing these posts, I spent this morning on preserving their legally certified copies for further proceedings in court.

As for all aspects of communication, with all participants of this incident (technical support Graviex, ARRR coin developers), they were also saved in full, but due to their larger number, they will be laid out for the public to evaluate in parts. According to them it will be possible to restore the chronology and the essence of the development of the conflict, as well as the opinion on this incident from the developers of the ARRR coin.
In addition, it will be possible to compare the nature of the attitude to the problem from the technical support of Graviex during the proceedings, where they did not hesitate to declare that the developers of the ARRR coin are fraudsters (the corresponding screenshots are also notarized in case of their removal from the Telegram channel).

Initially, I also saw the solution of this conflict in mutual movement towards each other - Graviex returns the funds to the account, and I, in turn, delete the posts and inform the public about the resolution of the conflict. However, further criminal behavior on the part of Gravks the theft of my funds, and even demanding an apology (??), which by any standards Graviex should bring to me, closes the possibility of further dialogue, in view of the inadequate position of Graviex. Apparently, Graviex will thus intimidate users in order to avoid publicizing such conflicts related to the loss of funds in user accounts - i.e. if you lost your money, be silent, otherwise you will lose more. The calculation is primitive and clear.

In this case, Graviex somewhat overestimated my attitude to the stolen funds. Now I am preparing material on this conflict with all the details, including in the legal plane. Public opinion on this fact will be fully formed in all information channels.
