I reported one of them 2 weeks ago
The answer from envato is below
“Thank you for reporting this potential exclusivity violation to Envato Market
We are currently investigating and will take the appropriate action if necessary”
they still did nothing 
I’ve been waiting for 1 month
for non-exclusive request
my account will be non-exclusive tomorrow
will there be any sanctions against those who violate the rule?
If not, are we stupid?
