Searching my IPs on google, today I discovered that all of them are banned from many websites that are using antispam plugins.
On of the most popular and effective is this one
https://wordpress.org/plugins/cleantalk-spam-protect/@Sven do you know it, or do you know how we can bypass it (maybe setting Ser to make just one post per account?), or please can you destroy it :D ?
For everyone that want to check their proxies and if they are banned by this plugin, use this website:

What I've done yesterday:
After all this job, I finally pushed START on Ser and went to sleep. Ser started to work at about 95 LPM and 50 VPM, and today when I woke up it was (is) still at around 88 LPM (past days it was around 30 LPM).
THere are still some error messages on the log, but much less than past days.
Hope it lasts long!
Yes, it's right! :-) Actually, around 90 LPM was the rate of only contextual projects, now that I'm running also "spam" projects the LPM is higher :D
