I of course can't speak for anyone else on the forum except myself, but I would like to mention I am not annoyed if the location in the title is outdated. (I mentioned it previously, but even if the location is outdated, it lets me know that the provider has traveled to my city in the past, and may return in the future. This is probably the least important benefit). I can think of 2 use cases where it affects me more:
1) For masseurs that are on masseurfinder, who do not have a unique user name. If those providers don't advertise on the other sites, then they are sometimes only referred to be their first name. Having the city in the title, helps me narrow down if it is the provider in my city. (Of course, it would be great if the original post provides a link to the masseurfinder page, or to the unique 5 digit number associated with the provider, but sometimes people forget to include those)
2) Helps me find threads that I may be willing to comment on. I am willing to provide feedback on providers that I have had the pleasure of having a session with. However, sometimes I won't recognize the user names of each provider I have hired. If the city is in the title, I can read through the thread, and maybe something will jumpstart my memory. I can now provide some feedback on the provider even if they are in another city that is not my own.
