Mike Rowe likes dirty jobs.
Even dealing with internet trolls.
If only they'd listen to his advice.
Consider limiting each blurb to a single entry. When you post the identical screed four times in a row, it looks very much like a broken record sounds. This will lead people to conclude that you’re either a) inept at posting, or b) deliberately obnoxious. Neither conclusion is likely to lead to a sale. Remember, most people see posts like yours as small piles of vomit that they can quickly step around. But when the same vomitus post appears multiple times, you force my friends here to slosh through a virtual lake of spew.
