Firstly, we would like to note that the majority of the website elements have explanations. If you hover your mouse over the element and wait a bit, a hint will appear:

And we would like to divide the very question to several points.
1. Any exchanger is present only at the versions of the website the support in the language of which it is ready to provide. Earlier we had written about it:
As you correctly noticed, Russian-language services are represented on the .ru version, and English-language ones on the .com version. This separation was made due to the difficulty of understanding a foreign language by the large majority of our website visitors. It must be noted that what is meant is not only the translation of the interface with which more or less a browsers in-built translator can cope, what is meant is firstly the language of support. If a service cannot provide qualified help in the required langue, such service is hidden from the corresponding version of the website. This is done mainly for the comfort of the very users.
2. Despite the fact that their profile is still in the catalogue, we do not show them for any exchange direction in cast it has a status different from "Работает" ("Available"). Some if the exchangers not shown in usual results due to technical reasons, can be found in the
general list, however the websites switched off by our moderators wont be shown them. It is mainly done so the users could have an option to leave reviews and have a dialogue in claims.
3. We do not publicly announce the reason for switching off, often it can be a temporality misunderstanding or an active unsettled claim from a user. If there are at least potential risks of not fulfilling obligations in regards of us or users, we exclude exchangers from the listing. And return them in active stated after they have solved the problem and eliminated the reason for the risk.
4. If an exchanger, in our opinion, cannot be restored in the listing, we add a label Warning! It may be unsafe to use this exchanger. Lots of complaints from clients, no response from the administration.
