If users upvote your posting by klicking the heart symbol

this adds to your “reputation”.
Additionally there appears to be a “reward system” that adds for example 200 “points” once your post count exceeds 20,000, regardless of what you have posted (including for example TripleA turn postings).
So “reputation” is the sum of all upvotes (maybe subjective quality, maybe a simple confirmation of taking notice) and quantity (mass posting reward), which - benevolently - might be interpreted as reward for long time membership.
