I will caution all members;
This group has a zero tolerance policy about mentioning agencies inside the country that "push paper" (help people get visas/extensions at the immigration offices). It is fine to mention agents in other countries that get visas from thai consulates and it is fine to ask about visa run companies that take people to the border or to consulates to get visas.
Mentioning or recommending in country paper pushing agents will get you blocked and banned, so DON'T do it.
The group is designed so people can ask questions and the many knowledgeable members can provide answers so you can do your own extensions and get your own visas.
I will also caution members NOT to accept private messages from other members (except admin/moderating staff).
With 23K+ members we have no idea if everyone is on the level. Be aware and be careful out there.
Also don't run with scissors ;) Thanx :P
TLDR : Answer Summary
The group has strict rules against mentioning or recommending in-country visa agencies that assist with paperwork for visa extensions. Members are reminded to avoid private messages from other members, except for admins, due to safety concerns. This is to maintain a supportive environment where members can seek help for managing their own visa applications.
