Support my pro se TCPA efforts

Hello, thank you for reading this. I have filed six TCPA cases, three in Small Claims and three in US District Court. I want only meritorious cases, and will not go after a business that stops calling as soon as I ask them to remove me from their call list. My cases have been against health insurance telemarketers, lower interest rate offers, auto warranty offers, and text message spam. I have many questions, that for me are either hard or slow to answer, and I look forward to learn from your knowledge in my quest to reduce robocalls. The areas I am trying to learn you run the gamut, but two* in particular will be the focus of our meeting: ○ Choose and act on an effective demand letter process ○ How much / how little to put into the complaint and other filings ○ Which defendant(s) to choose* ○ Service of summons, and other court papers* ○ Effective communications with defendants and their counsel ○ Deft negotiation skills ○ Moving through and beyond Discovery ○ Collecting *My specific need today is compelled by two questions 1) Whether I can follow the example of United States v. Palumbo, 20-cv-0473 (EK) (RLM), 2020 U.S. Dist. LEXIS 61466. Last Friday I got a Social Security Adm. fraud call and I want to decide whether to name the 'gateway carrier' (the one who brought the call into the US telephone system before it was transferred to my wireless provider) as a Defendant. This is what the US did in the Palumbo case. My challenge is they have access to USTelecom's ITG traceback process. 2) How I can move forward with my 100-text message complaint against 15 Defendants (the telemarketer / robotexter, ten businesses who advertise on pages controlled by the telemarketer, and four of those individual business owners.) I used Certified Mail (which I know is RARELY allowed for service of summons,) and would like to know if there is a good strategy to get any of them to waive service of summons before the case can begin. I also found a 16th Defendant and yesterday I asked them nicely to tell me the real corporation and registered agent. I suspect there is a wise strategy to engage them, but am not sure what is best. If you can help me with those questions, please let me know. I appreciate you reading all of this, and I look forward to working with you. Thanks, -Brett
