<human>: A few years ago, my profitable company was shut down (with 5 minutes notice), because the owning major media company wanted to fudge its bottom line for investors.

I really liked my old coworkers (still close friends) and job.  We were a small company, so there was room for a 23 year old in an entry-level job to get noticed and have an impact.

Well, I got a good resume from that.  I ended up doing quite well in the long run.  But, I had a couple months of shitty unemployment.

In my new job, I have control over many large online ad campaigns.  It's quite easy to block websites.  Only a few mouse clicks.  Campaigns can easily run across a few hundred thousand websites without anyone ever looking at a single domain.  My campaigns do well, so no one needs to double check anything.

So, I've gone out of my way to block said major media company a few times.  It has taken me longer to write this post than it has to block them.  But, it has cost them more than they made for liquidating my company.

I also make an effort to make sure their direct competitors get ads/revenue instead.

Through industry-related articles and events, I occasionally learn about their online ad struggles.

I've slowed down this practice recently (now that we're even).  If I have a bad day, a Fortune 500 brand may disappear from their site for a quarter...

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Got laid off by major media company, so I've make sure that major ad campaigns don't run on their websites, which is quite costly.
