The problem may recur (no guess as to how long it will take) while the 1200 anchor remains. Why not use provisional ratings rather than an anchor?
Given the Glicko maths works new players ratingis provisional. If win or loas player with freh 1200 it will not change your rating and his/her may well swiin 200 points. Just different kind of provisional.
(1) Are you certain that my rating does not change when I play against a new player? (2) Even if so, you have no idea how long it will take for a new player's rating to settle to its proper place; a provisional rating can get it near the true value very quickly. (3) Anecdotally, I have about 30 CC games here, and my CC rating is still about 300 points lower than it has been in the past under similar non-chess.com rating systems. I would need to play another 15-20 games for it to stabilize. If I had been provisionally rated it would have stabilized by now -and- the rating distortion to my opponents' ratings would not have occurred (or at least would have been much less).
I managed a chess rating system a long time ago. The starting rating is quite important. When a starting rating is assumed immediately from a new player's first game, then every game he plays distorts the rating pool (a little) until his rating stabilizes. But the distortion to the rating pool remains and is permanent. If you have a large influx of new players, the distortions accumulate across the population.
When a "provisional rating" is used, a new player is (1) given a rating estimate based on his play against opponents having established ratings (i.e. not other new players), and then (2) opponents' ratings are calculated based on the estimate. Distortion can still occur, but on average it is greatly reduced.
. Play me in live chess though

and what is kN/s in engines?
If you found your rating has dropped instead of increased, please write to support!

@tactiquero I fixed yours
Thank you very much for your quick response I suppose I could extend my membership for another year
@tactiquero, your new rating is bad. Your previous rating were 1835, and aplying the rule for 1800+ (400 points boost) , your new rating must be 2235, as every 1800+.
(vamos que te han "volao" 2OO puntos ;) ) Saludos.
