TLDR what is leftcom? Left Communists are people who say "real socialism has never been tried". Socialism requires the abolition of commodity production and money, exploitation, classes etc. No previous or existing socialist society has achieved this.

Yes, that is correct, but I was reffering to the socialism / communism distinction. They made a distinction between the lower and the higher phase of communism, but they did not make a real distinction between the words "socialism" and "communism" per se.
