Hello everyone 
Finally I am joining this thread…
First I truly apologise for the mess I did and the troubles and discomfort I caused – sorry. Especially I apologise to Stephan for the work and time he spent and will spend to fix my doings - sorry Stephan. After I checked his work here in OSM he got my full respect.
For me it is just an uncomfortable learning experience – for you it is probably just annoying
. Dear Stephan – maybe you can see the time that you spend as an investment to improve further contributions of a new (very) active member.
But before I start to explain what and why I did what I did – I think – it is time to introduce my self…
My name is Balthus (short Balts) from the german part of Switzerland
As I was born 1963 I experienced the whole process from analog to digital. As a young man I got very excited about this digitalisation of the real world and developed a passion for computer languages . After studies of Mathematics and Computer Science I worked 15 years as a specialist for Cryptography and IT Security for one of the big Swiss Banks. In these times I was also worked for an ISO Standard securing ATM transactions and Electronic payments. After 15 years and the upcoming PCs for everyone I lost interest for the digital work and quit.
Since then I do only seasonal jobs – first as a Ski instructor then as a Lifeguard. From 2000 I started to travel in South-East Asia – first mainly in Indonesia where I developed a passion for skin diving (free diving). After getting ear problems I needed to quit free diving and found a new passion – motorcycling – for which I came to Thailand. The last three winter seasons I did more than 30’000 km. As of now I stay in Thailand from October to March and go for work in Switzerland from April to September where I work as a manager in governmental recreation facility where we have up to 3000 customers a day.
In Switzerland I have a life of duties and social responsibility – here in Thailand I enjoy my freedom and social independency. I am a convinced single and do not have Thai «girl friends» here. At night – in general – I stay at home and follow my hobbies like astrophysics, photography and now OSM Thailand.
As you see I am not quite a regular Pattaya guy and that I have some sort of a double life – one in Thailand, one in Switzerland.
As you may noticed I never worked in an Online community and as a analog guy I have my difficulties to emotionally connect to a real person behind an user name. As I got in touch with Johnny, Russ and Stephan I have started now this «personalisation» process. Please be patient with me and still give me some credits.
I will do everything what is necessary to make this review successful.
As of now I already started to clean up my mess with the help of overpass turbo as I have learned from Johnny.
Job 01: Removing int_name, restoring name:en
Start: 26-Feb-2017 – Done: 27-Feb-2017
This was a quick and easy fix. Now the below query gives null results 
[out:xml][timeout:180];
(
node["int_name"](uid:136154);
way["int_name"](uid:136154);
);
out meta;
>;
Job 02 : Removing int_ref from Rural Roads and fix source
This is a more heave job as I touched many and I have to go them through one by one and the small bridges are a real pain in the a** 
Start: 27-Feb-2017 – Done: still work in progress
You can check the status quo with the overpass turbo query:
[out:xml][timeout:180];
(
way["highway"]["int_ref"](uid:136154);
);
out meta;
>;
Job 03 : Review of all my deletes (initiated by Stephan)
This is a delicate one. Could we do this bilateral Stephan through personal messages and just publish the results here?
Start: 28-Feb-2017 – Done: still work in progress
Job 04 : Review of all my given new references
This should be done mainly by future survey or current imagery from Mapillary as a source. By the way – as Johnny proposed to me some time ago – I finally signed up to Mapillary (as balthus-mc) and started my first uploads with road signs from my neighbourhood. I hope this will improve my future creditability 
…tbc
Please do consider – I still have a life outside of OSM – and that this review needs its time. Please do not rush Stephan. If we proceed step by step we won’t mess things more than before.
In my further posts I will also explain why I did what I did and how I did it. Maybe my problems could also lead to some clarifications in the «official» Thai wiki which could be a help for other contributors too.
By the way I am now planning a big tour around Isan in about 11 days following the geographical watershed and using mainly Rural Road – if I can. I also plan to document important road signs with Mapillary as much as I can – but I won’t spoil my riding experience because of it 
Okay??
Let’s go to work… Balthus
