The thing about most 'banned' records is that most became hits anyway, so banning them didn't really amount to much beyond shortening their chart/airplay stint, but in the end, most sold very well. The proof in that is in the charts: the Napoleon XIV novelty was only on the charts six weeks but got to #3, while "Eight Miles High" made it to #14 Billboard (two months on the chart).
Indeed, the only way to really kill a record would be if it were so appalling or depressing most stations wouldn't touch it. That's not a 'ban' in the strict sense, but a ghoulish little beast like the Jimmy Cross necrophilia ode "I Want My Baby Back" (an obtuse parody of "Leader of the Pack," where the Detergents (Ron Dante) "Leader of the Laundromat" was painfully obvious) was great fun to have hidden in your collection when you were a kid (as I did), and only got to the '90s in BB.
One forgotten hit that probably WAS hurt by stations refusing to play it was by none other than the Beatles, re "The Ballad of John & Yoko" in 1969. The use of 'Christ' in each chorus did the trick, and even offering a censored DJ version didn't really help (then again, even if it had been 'clean' it wasn't very much to brag about to start with).
As for Wiki, that list posted above is so dubious I won't even comment on it, other than to repeat, since most of those records were major hits, who or what banned them and where didn't amount to spit. Besides, a ban would have to be organized and pervasive to be effective, and such instances are so rare I don't remember one.
But since we've brought up some Leaders of the Banned, here's a vid clip, followed by the answer record (kinda):
