I am not seeing any restrictions on your account at the moment.
Question you want to ask your developer is , Is there a way to disable rand() function, This is the function that randomly displays the articles from reviewing the queries.
Please see the text below from one of the previous email we sent to you :
A large part of this issue due to the 'order by rand()' and subsequent 'limit' being applied to the results of a previous query. The 'limit' is not harmful, but has no benefit here, as most of the query's run time is spent performing a random re-ordering of 300+MB of data. Unfortunately, there are not many ways to resolve this properly, and we see that this may be a commercial script ('press release script').
Please let us know if you have any questions or require further assistance.
Thank you and have a great day,
