As recently suggested in my previous post "Will the DWG block us all one day?" I took a deeper look into it. I have scraped all 1934 user blocks available last friday together with some user information.
As already indicated, the DWG is blocking more and more user (< no judgement) .... probably along with the increasing interest in OSM and the influx of trolls and paid editors.
In May 2015 an user registered more than 100 accounts with names of public transport stations in Berlin and was blocked. In October 2017 around 60 accounts related with an education session called COMS2200A were blocked. During April 2018 29 accounts from GlobalLogic India were causing troubles and got blocked after a complaint in the osm.org user blogs.
If the trend continues, 2018 will be another record year of user blocks.
On the other hand, the median block duration is at a very low level. (in case someone does not like annualisation, here is a YTD May chart.
If you look who is blocked, you can see that the vast majority are newbies. A mapper is considered as new if the account age at block date is less than 6 months. (If one is blocked more often, he could fall in both categories) However, experienced mapper blocks are also on the rise slowly on average.
The average block duration (chart in months) seems to be unrelated to the mapper type. The spike in 2014 is mainly caused by the 100 years block of user Sorein. In 2016 emacsen blocked some new users for 10 years which resulted in the other spike. Example
[irony] Just in case there are some troubles with the DWG (I am looking into it for a friend), you may want to know whom to avoid. [/irony]
The chart shows the average block length in months. The bubble size represents the number of blocks made. DWG stand for the OSMF Data Working Group account. They blocked 6 accounts for 9 years, all belonging to one criminal case. The other outlier is emacsen, which -as mentioned earlier- blocked someone forever. So let's leave this aside.
[irony] In case you are in trouble, you should avoid Peda, SomeoneElse and woodpeck if you are a new mapper. Try pnorman instead. If you are already a while around, SomeoneElse seems to be a better choice than pnorman and woodpeck. [/irony]
