I know that direct advertising is not allowed on here (quite rightly) but when I see posts like this

"Often times, the most inspiring stories are those that involve struggle, insurmountable challenges and real people. Like climbing a mountain or breaking a record, we are all inspired by people who relentlessly chase success and refuse to give up. That’s why cutting-edge businesses are turning to the best motivational speakers (link removed) for their expert advice on teambuilding, leadership and business solutions"

This reads like a PR statement and so I pressed the spam button but as nothing has happened so do I assume it is acceptable?

And speaking of PR, what is the protocol for posting 'research' which is glorified advertising.  I appropriate the boundaries can be blurred when a firm publishes its own research mixed with lots of quotes and references to the firm but should we be slightly more discriminating on this forum for allowing this.
