I find the ads about non-mathematical things annoying. I tried to click on one to report it but nothing worked. Is there a way a user of Stack Exchange can get rid of such ads? Some seem to appear for a few days and then go away, others then appear a few days later. Thanks for any information.
Added: One such was "Enterprise Flash Storage Solutions" which had an IBM logo on it. It seemed to be about some technology involving use of "clouds" which to me is not math at all.
