Of those 3,308 stocks that were suspended, I know of only 7 that have managed to claw their way back to resume trading normally again:
EDVP (now PRLX)
SDRG (from Sept. 17,2012 SEC Suspension), but SDRG ended up getting suspended again after that
PHOT
GSTN was reinstated to the OTC by FINRA. It was originally suspension by the SEC for questions about adequacy and accuracy of information on May 14, 2012
DHCC re-registered with the SEC on Oct. 14, 2015 after the stock registration had been revoked on Sept. 14, 2014
FTNW re-registered with the SEC on Feb 7, 2017 after the stock registration had been revoked on Sept. 12, 2014
CANN re-registered with the SEC on Dec. 23, 2016
7 out of 3,308 is a very very small percentage, so no matter what the company or other shareholders tell you after your stock has gotten suspended, there is almost no chance that the stock will ever get off the Grey Market or get re-registered with the SEC and go back to trading normally again.
