Well, i can assume it is penalty 100%.

To not get penalty again after weeks-months on new moved domain, you should fix reasons of that.

It can be:

Duplicate content;
Translated content;
Adding many pages daily by auto plugins (embedders);
Until site does not has organic traffic - adding ads, popunders, affiliate links.

Nothing knows exactly the reason of that penalty.
