My 2 cents in this telegraph short email
#1 it is a common situation in Bosnia&Herzegovina and Croatia, likely in other CEE countries of CEE where providers are 'cheap' with IP addresses. I know an amazingly constructive and dedicated, but not proactive editor who failed to get unblocked on EN, as he could not explain as a novice to EN admins in 2015 that he was not a sock puppet . Loss is on our side.
#2 This is a complex (and for outreach mission critical) problem that requires real-time addressing and most likely a dedicated paid professionals (better 4 x 50% across time zones) to take the burden off from voluntary stewards and admins, but also to inform and educate those who could not follow what are common network issues across different regions.
Best, Z.
