/r/UkraineRussiaReport is basically the only forum on the whole site where anything that isn't 100% cheerleading for Ukraine is allowed to be posted. It seems like pro-Russian propaganda only in contrast to the rest of Reddit where the pro-Ukraine bias is actively enforced by the mods. You say the creator was "called out" on other subs which is why he created the alternative. But that just lends legitimacy to the sub, if you're interested in anything approaching an unbiased source of information.
