In all fairness having three or four new threads posted on the same day, recommending and encouraging purchases of a book, just after the authors thread had been deleted, all being posted by members of 'the other big bass forum', is pretty much the definition of spamming.
Although those posters were TB members, it wouldn't take a genius to work out what's going and have a quick look on BC and find this thread, especially given the response by TB to the original thread by the author.
Fair play for trying though but I feel to many threads were started in the rush to help.
That said it's a shame TB is the way it is, but it is.
