That was a LONG time ago. Their entire ruleset and moderation approach changed more than once since then.
The thread below shows you some examples of land claim issues that could potentially get you in trouble. However by your description it was a megabase with all altars and everything so there’s a high likelyhood you were taking up more space than needed (as in, some of it didn’t serve a functional purpose by their definition and was only there claiming land)
Their policy also isn’t to give out warnings or send you any email about it. If you get reported and they go to investigate and find something out of order, the base will be wiped and the entire clan suspended from official servers on the very first incident. (which will be longer on each subsequent suspension until you get a permanent ban)
