Normally members are not supposed to be able to create threads in Sponsor Forums, but due to a permissions snafu this one got through. Vendors have full moderation control of their own dedicated forum, it is for their news, promotions, etc. This thread was initially deleted as Vendors get local moderator permission of the area they pay for and rightly so. However the user has threatened to delete his account due to 'site censoring' so I've taken another look at this and spoken with BMS. The truth behind the thread deletion is:
1) Vendor forums are not for people to smear the vendor's brand
2) The vendor believes they could have approached the question a bit better
The deletion had nothing to do with silencing the customer, in fact they were doing him a favor because this is embarrassing to read. If you know how AN fittings work and understand if you have a 4mm ID restriction on one end of a connection, it doesn't matter how big your hose is.
