Russia has added more online gambling operators to its payment processing blacklist, but it remains to be seen what success this tactic will achieve.

On Wednesday, Russian gambling affiliate Bookmaker Ratings reported that the Federal Tax Service (FTS) had added 16 names to its list of companies with which Russian financial institutions are forbidden to do business. The FTS announced last month that the Curacao-licensed online casino Azino777 was the first company added to this list.

The newly blacklisted names include four locally familiar gambling faces: Baltsport NV (Baltbet), Betcity Network NV (Betcity), Pari-Match NV (Parimatch) and Leon International Ltd (Leon). All four hold Russian online sports betting licenses but also operate internationally-licensed sites that offer casino, poker and other gambling products that remain illegal in Russia.

Betcity’s Russian-licensed site ranked fifth on the country’s 2018 online bookmaker web traffic report, while Parimatch (6th), Baltbet (7th) and Leon (8th) also scored above-average positions.
