Why shouldn't you trust solicitors? Because usually they don't have your best interest in mind. Most often, they have only their interest in mind... which is only to make money or some other benefit.
If we look around and think about it, this is something many of us have learned over time dealing with car dealers, telemarketing reps, door-to-door sales and services, junk mail sent to our postal box, and with new technology such as email we are learning not to trust what's sent to our inboxes unless we asked for it as well.
Let me clue everyone in on another solicitor not to trust. If you have ever had a website or maybe you had a domain name you purchased online, its very possible you have been solicited at one time or another, by individuals or companies for their services. Their service descriptions vary a bit and some seem very professional but bottom line is these people are comparable to the ambulance chasers in the law and accident world and are just looking to make a quick buck off someone.
It first started with emails from companies looking to sell me other dot variations of my current domain name so I could "secure" my place on the Internet. Ok, its not a bad idea for branding security to do this but not everyone needs to have a ".biz" or ".me." or ".org" however. So, I considered maybe getting more and did some research with those offers. Every one of them was a MUCH higher price than my current web host was already charging for same service.
Basically the solicitor was hoping I thought their email was an emergency in securing my brand and would take them up on their offer without shopping. Its shady advertising to me and thus I also don't know if I trust any transaction either. So I started glossing over most other offers... even those that came in postal mail.
Its merely an example of those trying to take advantage of people that are not willing to research or maybe a little gullible in nature. One just has to remember that there are people out there wanting to sell you services for exaggerated amounts when you can get the same services through your current web hosts and domain registrars for a fraction of the cost and feel safer doing it.
