The more data uploaded to the chain the more space the chain takes in memory.
The nodes need more memory to hold it all.
That was a real problem before @blocktrades and crew reduced the footprint of the data, exponentially.
In the beginning, nodes were very expensive, now, not so much.
So, the need to punish spam, and 'low effort' posts was based on the costs associated with them, ie, bigger nodes, more expense to keep the chain functioning.
Those days are gone, but control freaks are gonna continue to control.
Some compulsively.
Fraud is something different.
Presenting work as your own and profiting from that is questionable behavior in polite company and currently not allowed rewards in the hive by 'the community'.
I don't imagine folks will ever stop flagging that.
