There are some managers who bulk upload transcriptions of registers. If a cemetery had very few entries and suddenly appears to have thousands that's usually the reason, clicking on a few of the memorials will reveal who the manager is and their profile will show how many memorials they have created and how many they manage. Corrections offered can be accepted or rejected by a manager, if ignored they are auto accepted after a period of about 28 days (I can't recall the exact timeframe). Some managers are really good and deal with corrections promptly, some are a little slower to respond, some ask for documents/supporting evidence before accepting them.
The bulk uploads may be light on detail as the registers themselves rarely have maiden names for example and even if burials of the same surname appear in the same plot the multi million manager types rarely research the names to link them together as family groups.
I've had good and bad experiences, it's not the site as such, more the attitude of those using it and the way they sometimes use it, that goes not only for managers but also for those submitting corrections. I've had numerous corrections offering maiden names to memorials I've added but sent as private messages, where a name applies to duplicate memorials it's often difficult to tell which memorial is being referred to. If the 'suggest edits' was used then it's much easier as a manager to go through them.
