Used to happen when I was a runner. Something about loose cheap cotton shirts, humidity, and sweating. Doesn't happen while cycling because I wear jerseys that fit properly. I've never had an issue with bib straps causing problems.
Always interesting to see which members have been banned on these old threads and sift through the banned user list to try to figure out what happened. Usually their offensive posts have been deleted so you can only guess. Often, the mods did not update the banned user thread with their name so you can't figure it out.
In this case, Chasm54 apparently self-imposed the ban, which is a thing that they used to do.
And it will be interesting to see if this thread gets locked and/or disappeared. It's very arbitrary and random as to what They decided to do with these zombie threads.
