If that was the reason then they never really did this.

All the large divisions within IB that run vBulletin have their own full time developers, and pretty much run their own heavily modified version(s). They dont really have any contact with VBS and I dont see that it would make much difference to them who actually owned vB itself.

^ Now that Paul mentions it, if you all recall a majority of the IB sites at the time they purchased vBulletin (the larger boards) were running and still run vBulletin 3 instead of 4 or 5.

Lol so much for worrying about the plugin system, https://vborg.vbsupport.ru/showthread.php?t=313021

Security issues happen, regardless of who codes what.

The plugin system is a legit nightmare when someone figures out how to take advantage of it.

I've actually started visiting TAZ again since they updated their forum software. I think they made the right choice. ;)

I doubt anyone left TAZ because it ran on vB3.

I 100% agree and it's something the costumers have been saying for years now.
I never said they did.. But it's a lot more welcoming and actually pleasant to use since they upgraded.

With vb 5 it seems like security issues are occurring at an alarming rate.

Whereas xenforo on the other hand, has never had a security issue during all its years of existance. That speaks volumes.

Well its "years of existance" have not been that many yet.

People used to say exactly the same about Linux v Windows.
As it grows and becomes widely knowm, its only a matter of time before the hackers start to target it.

It will... With certainty. Its just a matter of time. As Paul said. Look at apple. Macs used to have the reputation of being virus proof, when it was just that hackers preferred to hit windows based machines as they are 95% of the market. Its nothing against Xenforo, its just the nature of things.
