I think so. Most ITK's are driven out of town by people who expect detailed and complex deals to be pushed through immediately and cannot fathom why they might stall or fizzle out. The burden of proof placed on most ITKs just keeps getting more and more ridiculous.
It's a shame. If people don't believe the credibility of someone who passes on info they should just ignore it and put the person on ignore, unless it's beyond obvious they're lying.
Many people enjoy being able to hear what some ITK's say, knowing it may not all pan out but too many toxic posters want to drive any ITK out of town unless they have a 100% hit ratio.
Just a bit sad that some people enjoy taking potshots at people giving information, while spoiling it for people on the forum who enjoy hearing what ITK's have to say.
