Wait wait wait you did your PhD with Haspelmath???

Yep. 2008 in Leipzig.

Most or all bilingual varieties of the languages spoken in the area between Sri Lanka and Greece have bilingual compound verbs, consisting of a lexical content verb from a donor language and a helping verb from the matrix language. In this paper, these verbs are described and analyzed, and the question is raised whether this widespread occurrence is specifically an areal feature, or a universally available pattern and a question of typological poise—the possibility of a construction arising due to propitious typological circumstances. Pleading for the areal perspective, it is concluded there is the fact that two large and important language families—Turkic and Indo-Iranian—either rapidly developed or already had a productive [noun + verb] construction. On the universalist side, it is clear that native [noun + verb] constructions very easily develop into [verb + verb] constructions in bilingual settings, though not in monolingual settings. This is a cross-generational change that is a contact phenomenon; that is to say, this development does not occur in monolingual, non-contact language settings.

I saw your comment on lalalangkornreis's post about "(ge)rebloggt" and I still can't think of a plausible explanation for the form with "ge-". First I was thinking that maybe "rebloggen" only /looks/ like the result of a derivation with a prefix and was actually imported from English as a whole, so to say, thus making the form with "ge-" perfectly regular. But looking at other loanwords with "re-" (like reparieren, residieren) I found that they don't have the Partizip with "ge-" either. ?

Interesting question.

The difference between the examples you cite is that the other loan verbs came from/through French and their prefix {re-} has (often) been analysed as such by analogy with unprefixed verbs like parieren : reparieren, kapitulieren : rekapitulieren. Furthermore, these verbs carry the loan verb marker {-ier} which puts all of them into their own inflectional class (alongside only a handful of verbs derived from native stems like buchstabieren, hofieren). This loan verb accommodation mechanism is at least 800 years old. 

The form rebloggen is much younger and comes from English. We do have bloggen as well, which has most likely been incorporated into German a couple of years earlier than rebloggen, so one would expect that the {re-} become analysed, too. 

The crucial point is not whether these verbs are borrowed or not but that they carry a prefix. Native verbs with some sets of prefixes like {ver-}, {ent-}, {er-} do not form their participles with {ge-}: verbiegen > verbogen, verstehen > verstanden, verkaufen > verkauft, entstehen > entstanden, erschöpfen > erschöpft, erstehen : erstanden etc. The prefix {re-}, though borrowed, has been added to this group of prefixes. 

A possible motivation to add {ge-} for rebloggt nonetheless could be the desire to distinguish the form from the homonymous 3.SG.PRS form. 

I am sure @modalauxiliary can shed some more light on that.
