Thank you for your time and the motivation, MojoJojo .
I think you are right, maybe I had bad luck with the account seller, even though he was recommended by someone who bought hundredes acc.s. from the seller (proxies are from Massproxy, but those of dma.0245, too. Sim cards are physical ones, bought from a recommended seller here. I am using only 1 per acc., so proxies and Sim cards are likely not causing an issue).
Will definitely think about your kind words and if I make it on the IM HORSE , I wont forget your contribution to it and will be also then a motivator for others.
Thank you also for your nice words, Ian. Will also reconsider that! All the best to you and your accounts!!
