It seems like gboysiam, gboy69, and gboyzab are all offline now.

Does anyone know where these freelancers are advertising now?

I would like to know too :-)

You can find a lot of familiar faces on Twitter if you search hashtags like #ชายแท้รับงาน

Gboysiam can now be found under a new name at :
www.violetball.com

Excellent, thanks!

Looks like Violetball is gone already. That didn’t take long.

Violetball is back now, but requiring a membership fee.

violetball is gone already. Any new website?

If there is one I haven’t found it.

But there are lots of boys advertising on Twitter if you know what hashtags to search for — such as #ชายแท้รับงาน.

I stumbled on a twitter account which seems to be linked with the now defunct violetball.com website ; unfortunately no activity on this account since July 2020.

Gboysiam still seems to exist but is now in CHINese! Seems linked to that gaythaicool.com site that describes various m2m massageshops, older ones advertising on TMB=ThaiMassageBoy site, newer ones the many that have sprung up in Sapan kwai.
Setting it in dr. googles translations delivers some funny results.
About subject of this very old thread-no idea. Christian states he does it mostly via line etc.
